article: A football club chairman has warned of a new breed of hooliganism in the sport – from retired grandfathers who are trying to relive their youth and encourage violence on match days. Dave Doggett, the boss of League Two outfit Cambridge United, believes groups of up to 10 men - aged in their 50s and 60s - are trying to relive the 1980s by arranging fights with rivals prior to games. He said violence at matches has increased recently as the older men return to watching their team play in their retirement and fears there is a danger that they will try to encourage younger fans to join their 'gangs'. Scroll down for video . Dave Doggett, the chairman of Cambridge United, has warned of a new breed of hooliganism and believes groups of up to 10 men - aged in their 50s and 60s - are trying to relive the 1980s by arranging fights with rivals . Mr Doggett said violence at matches has increased recently as older men return to watching their team play in their retirement and fears there is a danger that they will try to encourage younger fans to join their 'gangs' Writing in his club's latest programme, Mr Doggett said: 'Unfortunately football clubs still attract an undesirable element of society that appear determined to ruin the enjoyment of real supporters of football clubs. 'Our promotion to the Football League appears to have encouraged our "risk" from the 1980s to come out of retirement. 'Many of them are grandparents trying to encourage the next generation to join their "gangs". 'It sounds pathetic but unfortunately it is reality. We are working closely with police. 'Hopefully the reality of the potential consequences will dissuade some of our younger supporters from becoming involved with these undesirables. 'Our football club is too important to so many to allow a few to ruin our great sport.' Peter Woor, a Cambridge United fan, said he had noticed that the hooliganism of the 1970s and 1980s still lingers in games against local rivals such as Southend United and Luton Town. He said: 'There's a tension and you feel threatened so I don't go to those places anymore. It's not worth it. 'Most places are fine though, but you still tend to go to away games and keep your colours hidden. 'I remember the 1970s and 1980s and it was horrendous and of course it's nothing like that but it's still a problem. 'These people must have something missing in their lives to want to do this. It's very sad.' Cambridge supporter Simon Dobbin, 42 (pictured with wife Nicole), remains in a medically-induced coma since being attacked after an away game to Southend on March 21. Police said he was an 'entirely innocent victim' Mr Doggett said older men were those causing violence.

One Cambridge season ticket holder, who asked not to be named, said a group of about 30 fans regularly turn up to games looking for trouble afterwards. He said: 'They arrive after the game starts and then leave before it finishes to find a fight.' Cambridge United supporter Simon Dobbin, 42, remains in a medically-induced coma since being attacked after their game away to Southend on March 21. Essex Police said he was an 'entirely innocent victim' and believe he was set upon by a group of thugs intent on attacking the visiting Cambridge fans. Cambridgeshire Police said the force has also seen an increase in the 'severity and volume' of football-related disorder this season. Inspector Steve Kerridge said: 'We have seen an increase in football-related violence and disorder amongst a very small minority of people, both in Cambridge and other locations when the club has travelled. 'The tragic events recently leading to a serious injury in Southend have been reported widely and sicken us all. Mr Doggett said Cambridge United had noticed an increase in violence since the club was promoted to League Two last year.

'The club is working hard with us to ensure that those who use football as a vehicle for violence and disorder have no place in the terraces or association with Cambridge United.' He said police are using football banning orders, which impose 'stringent court-backed' restrictions on individuals. He added: 'The increase of risk activity both in severity and volume this season means regular consideration of this level of intervention is once again - and sadly - justified and necessary.' The warning comes as football chiefs across the country continue to promote the Kick It Out Season of Action campaign to promote respect within football.
