And today Milan Mandaric vowed to investigate whether action could be taken to get the club's crest taken off the cover of the book Rolling with the 657 Crew.

The book, being written by Cass Pennant, the former leader of West Ham hooligans the Inter City Firm, celebrates the actions of the 657 Crew, notorious throughout the 1970s, 80s and 90s.

Pompey chairman Mr Mandaric said: 'There's nothing we can do about the club's history but times have changed. Our supporters go away in their thousands and are well behaved.'

Police fear the book could attract young football fans into becoming the next generation of matchday troublemakers.

A spokesman for publishers John Blake said the company had published several books by Cass Pennant and did not view them as glorifying hooliganism.
Planning mayhem by e-mail
PORTSMOUTH hooligans make no attempt to hide their plans for violence before, during and after matches on a website.
Just an hour before Saturday's game kicked off one yob emailed the site to say Stoke fans were packed in a pub in the centre of Portsmouth.
More than 130 police were called out to patrol the game between Portsmouth and Stoke.
After the match one yob spoke on the site of his sadness that the game passed peacefully.
When fans were Britain's worst
THE infamous group got its name from the 6.57am train from Portsmouth Harbour station they would use to travel to away games.
Their behaviour led to Pompey fans being branded 'the worst in Britain' by Plymouth police after violence in March 1981.
In one of the worst incidents involving members of the 657 Crew, they set fire to a stand at Huddersfield Town in May 1985. It happened as more than 50 fans lost their lives just 20 miles away at Bradford's Valley Parade ground.
Another black day in Pompey's history occured during an FA Cup tie in 1984 when 10,000 Southampton fans travelled to Fratton Park. Dozens were arrested and many injured during pitched battles after the match.
