A number of arrests were made today during crowd trouble at the FA Cup fourth-round tie between Hull and Millwall.
Supporters at the KC Stadium reported seeing seats ripped out and used as missiles as a section of Millwall fans tried to get to their Hull rivals at two stages during the match.
Police in riot gear quickly joined stewards to deal with the trouble which first broke out before the kick-off in a corner of the North Stand where the away fans were closest to Hull supporters in the East Stand.
In the second half, a further incident was spotted in the other corner of the North Stand which was packed with Millwall supporters who had made the trip from London.
At the end of the match, which ended as a 2-0 victory for the home side, police horses patrolled the touchline as thousands of Millwall fans were kept behind by the police.
Some of those in the 18,639 strong crowd said the atmosphere was tense from the start when Hull paraded their new £5million signing Jimmy Bullard on the pitch. The former Fulham player was met by a chorus of boos from the Millwall fans.
Tonight, Humberside Police said they could not yet give any details about the number of arrests as they were still dealing with the incident.
A spokesman said further details should be available later.
Millwall manager Kenny Jackett said: ``There were one or two rushes and then towards the end of the game you see the police horses come out. I don't think it was off-putting for us.''
