In August 2011, a horrifying double murder inside a luxury London hotel shocked investigators and stunned the public. What initially appeared to be a chaotic crime scene involving jealousy, alcohol, and rage would soon transform into one of the most disturbing murder investigations in modern British criminal history.
At the center of the case was a respected hotel manager named Attila Ban — a man coworkers described as kind, hardworking, and impossible to hate. But behind that friendly image was a dark obsession that ultimately ended in bloodshed.
A Grim Discovery at a Luxury London Hotel
On the afternoon of August 10, 2011, Detective Inspector John Finch of the London Metropolitan Police arrived at the Radisson Edwardian Hotel in London after hotel management reported a horrifying discovery.
The luxury hotel, known for its upscale atmosphere, koi ponds, and elegant restaurants, also contained staff apartments where employees lived. One of those apartments had become an active crime scene.
Inside, police found the bodies of two young hotel workers:
- Alice Adams, 20 years old
- Tibor Vass, 20 years old
A third resident of the apartment, 31-year-old hotel manager Attila Ban, was missing.
At first, investigators had no idea whether Ban was another victim, a witness, or the killer.
The First Crime Scene: Alice Adams
When Finch entered the apartment, he immediately encountered a brutal scene.
Alice Adams lay in the living room in a massive pool of blood. She had suffered numerous stab wounds, and a couch cushion had been placed over her face. Although she wore a shirt and underwear, her pants were missing, raising suspicions of a sexual motive.
Blood covered nearly every surface.
Investigators also noticed alcohol bottles and pills scattered throughout the kitchenette, suggesting the group had been partying heavily the night before.
To Finch, the murder initially looked like a crime of passion fueled by intoxication and emotional rage.
Tibor Vass’s Body Told a Different Story
But the bedroom revealed something even stranger.
Tibor Vass was found completely naked and carefully posed on the bed. Unlike Alice’s chaotic murder scene, Tibor’s body appeared almost staged.
Detective Finch immediately noticed several unsettling details:
- Tibor’s body was unusually clean
- There was very little blood on the bed
- He appeared to have been washed
- He suffered only two stab wounds
- Both wounds pierced directly into his heart
The contrast between the two victims confused investigators.
Alice’s murder looked impulsive and frenzied.
Tibor’s looked methodical and deliberate.
It almost seemed as if two completely different killers had committed the crimes.
Who Was Attila Ban?
As police interviewed hotel staff, they learned more about the three coworkers.
Everyone described Attila Ban as an outstanding employee. He had recently been named Employee of the Year and was well-liked throughout the hotel.
Coworkers also explained that the gathering in the apartment had simply been a small celebration for Tibor, who had recently been accepted into college.
Only five people attended:
- Attila Ban
- Tibor Vass
- Alice Adams
- Two additional coworkers
The two coworkers told police the night involved heavy drinking but no fighting or arguments. When they left the apartment, all three remaining guests were alive and behaving normally.
Still, Attila’s disappearance made him the obvious suspect.
But nobody wanted to believe it.
A Possible Love Triangle
During interviews, detectives learned that Alice Adams had a boyfriend, although coworkers believed she had grown close to Tibor.
Some described flirtation between the two.
This led Finch to briefly consider another theory: perhaps Alice’s boyfriend had arrived unexpectedly, discovered the pair together, and murdered them in jealousy.
However, surveillance footage from around the hotel quickly weakened that theory.
The cameras captured:
- The five party guests entering the building
- The two coworkers leaving later that night
But Alice’s boyfriend never appeared on camera.
More importantly, there was still no sign of Attila Ban leaving the building.
The Detail Detective Finch Couldn’t Ignore
While leaving the apartment after his initial inspection, Detective Finch noticed something deeply unsettling.
There was blood everywhere inside the apartment.
But none outside.
No bloody footprints.
No blood trail.
Nothing.
At the time, Finch pushed the observation aside so he could focus on interviewing witnesses. But the detail would later become the key to solving the entire mystery.
Because if nobody left the apartment covered in blood…
Then maybe the killer never left at all.
The Chilling Discovery Two Days Later
By August 12, Attila Ban was still missing.
Police traced his phone signal to a cell tower near the hotel, suggesting he might still be somewhere on the property. Yet repeated searches uncovered nothing.
Detective Finch returned to the apartment with his team for another sweep.
Almost immediately, something felt wrong.
Finch noticed a vodka bottle had been moved from its original position. Then another investigator pointed out that the bedroom door — previously left open — was now closed.
When they tried to open it, something heavy blocked the door from inside.
The detectives forced the door open.
Inside, they finally found Attila Ban.
He was lying face down on the bed, naked and covered in blood.
But the real horror was still unfolding.
The Killer Had Been Hiding Inside the Mattress
Investigators eventually uncovered the terrifying truth.
After murdering Alice and Tibor during the party, Attila Ban did not flee the apartment.
Instead, he used the same knife to cut open the side of the mattress in the bedroom.
Then he crawled inside it.
For two full days, while police searched the property and forensic teams processed the apartment, Attila remained hidden inside the mattress only feet away from investigators.
The moved vodka bottle and barricaded bedroom door were signs he had finally emerged from hiding.
Why Attila Ban Committed the Murders
Police determined that Attila Ban had been secretly in love with his roommate, Tibor Vass.
During the party, Attila allegedly saw Tibor kissing Alice Adams.
The sight sent him into a jealous rage.
Investigators believe Attila first attacked Alice in a frenzy before turning his attention to Tibor, whom he killed more carefully and deliberately.
The unusual positioning of Tibor’s body appeared deeply personal, possibly reflecting Attila’s emotional fixation on him.
When Attila later attempted suicide, he arranged his own body in a similar pose beside Tibor.
Attila Ban’s Arrest and Conviction
Despite severe blood loss from cutting his wrists, Attila survived.
Police rushed him to a hospital, where he received medical treatment before being formally arrested.
He was later convicted of murdering both Alice Adams and Tibor Vass.
Attila Ban received a 26-year prison sentence.
Why This Case Still Horrifies People Today
The Radisson Hotel murders remain one of the most disturbing criminal cases in recent British history for several reasons:
1. The Killer Hid at the Crime Scene
The fact that Attila Ban concealed himself inside a mattress while police investigated only feet away feels almost unbelievable.
2. The Crime Scenes Were Completely Different
Alice’s chaotic murder contrasted sharply with Tibor’s carefully staged body, confusing detectives and making the case far more difficult to understand.
3. Nobody Suspected Attila
Coworkers consistently described Ban as friendly, hardworking, and gentle. His reputation made it difficult for people to imagine him capable of violence.
4. Detective Finch’s Observation Solved the Mystery
The missing blood trail became the critical clue that eventually revealed the killer had never left the apartment.
Final Thoughts
The 2011 Radisson Hotel murders stand as a chilling reminder that appearances can be dangerously deceptive.
What began as a simple college celebration between coworkers ended in obsession, jealousy, and unimaginable violence.
For Detective Inspector John Finch, the solution came down to noticing one small inconsistency — the absence of blood outside the apartment door.
That single observation exposed a killer hiding in plain sight.
And for two terrifying days, Attila Ban remained concealed just inches away from the investigators searching for him.
