Six men arrested over the death of a football fan attacked outside Wembley Stadium before Tuesday's Euro 2012 qualifying match between England and Wales have been bailed, police said on Wednesday night.
Wales supporter Mike Dye, from Cardiff, was beaten to death outside the stadium before kick-off in the Euro 2012 qualifier which saw England beat Wales 1-0.
The men detained in connection with the incident, aged between their late 20s and early 40s and all believed to be Wales supporters, will return to speak to police officers again on dates in November, Scotland Yard said.
The 44-year-old victim, was found with head injuries on a concourse area outside the turnstiles at the venue at around 7.20pm on Tuesday. Paramedics revealed he had also suffered a heart attack before being rushed to a north London hospital.
Colleagues at Cardiff Council, where Dye worked in the highways department, were said to be devastated
Council chief executive Jon House said: "Staff at the authority are devastated at the loss of their colleague and friend who gave almost 20 years of good service to the Council in a very specialised service. Our thoughts are with his family at this tragic time and we will be offering support to his family and work colleagues."
Thousands of people have left messages on a Facebook tribute page entitled RIP Mike Dye, known to many as Mikey. The victim was a long-time Cardiff fan who wrote about the Bluebirds on the CardiffCityForum internet site. Tributes were also left outside the Bluebirds' home ground, Cardiff City Stadium.
Police continue to appeal for anyone who may have witnessed the attack to come forward.
A police spokesman added: "Officers from the Homicide & Serious Crime Command are investigating, and inquiries continue to establish the full circumstances of the incident. An incident room has opened at Hendon under A/DCI Sheila Stewart (HSCC).
