A fan beaten to death outside Wembley Stadium before last night's soccer international was named by police today.
Wales supporter Mike Dye, 44, of Cardiff, south Wales, was attacked outside the stadium before kick-off in the Euro 2012 qualifier which saw England beat Wales 1-0.
Six men - all believed to be Wales supporters - are being questioned by police about the incident.
Mr Dye was found with head injuries on a concourse area outside the turnstiles at the venue at around 7.20pm last night.
Paramedics revealed he had also suffered a heart attack before being rushed to a north London hospital.
Colleagues at Cardiff Council, where Mr Dye worked in the highways department, are said to be devastated today.
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."
