The British Transport Police (BTP) is hosting a national summit on the best way to tackle offending linked to football hooligans.

While violent crime of this nature is down, "casual, thuggish behaviour" is becoming more common, according to chief constable Paul Crowther. There are also concerns that football-related crime is being under-reported due to witnesses and victims being too scared to come forward.

Overall, 630 incidents have been reported to the BTP since the beginning of the current season in August. Of these, 162 are believed to be racially or religiously motivated.

The move comes after footage emerged of Chelsea fans appearing to push a black man off a Paris Metro train in February after an away match, chanting "We're racist, we're racist and that's the way we like it", prompting widespread public outrage.

The summit was deliberately scheduled to take place the day before the FA Cup semi-finals, which 400 BTP officers will be required to police.
