A murder investigation has been launched by police after a Welsh football fan died following an attack outside Wembley stadium.
Six men, also believed to be supporters of the international side, were arrested in connection with the incident that took place just 25 minutes before the kick-off of England's Euro 2012 qualifier against Wales, Scotland Yard said.
The victim, 44, was found with head injuries on a concourse area outside the turnstiles of the north London sporting venue at around 7.20pm on Tuesday night following reports of an assault.
Paramedics said the man, named by fellow football supporters as Cardiff City fan Mikey Dye, also suffered a heart attack before being rushed to a north London hospital.
A Met Police spokesman said: "Police were called at approximately 7:20pm on Tuesday, 6 September, to an area outside Wembley Stadium following reports of an assault.
"Officers and London Ambulance Service (LAS) attended. A man, believed to be aged in his 40s, was taken to a north London hospital suffering from head injuries. He was pronounced dead at 8.50pm.
"Police believe they know the man's identity, but await formal identification and confirmation that all next of kin have been informed. A post mortem will be scheduled in due course."
An LAS spokesman said paramedics on standby at the match were on the scene within three minutes, before the victim was taken to hospital in an ambulance belonging to a private medical contractor employed by Wembley.
"LAS staff treated a 44-year-old man who had suffered a cardiac arrest. Extensive efforts were made to resuscitate the patient and he was taken to hospital," added the spokesman.
Menish Huseyin, 29, who was working on a merchandise stall outside the stadium, told reporters: "It's really shocking news, most games go off without a hiccup. It's really disheartening that someone was coming to a football game and being killed. It's very cowardly."
