I witnessed incidents at both venues and the violence at Wembley was far more serious than the posturing at Grimsby, those involved in London could have been easily identified by CCTV images and seat numbers, but to my knowledge, nothing happened to them.
It shows the quality of Saturdays Policing when, out of all this serious disorder and mayhem, there were just four arrests for Section 5 public order?
The Police themselves were complicit in the disorder, as they have sent away fans (Men, women and children) over the footbridge and sea wall on many previous occasions, invariably with the same result. I remember explicitly the identical scenario a couple of years ago when Leeds came to Blundell Park in similar numbers. The local morons go straight to Suggitts Lane crossing, grab handfuls of stones off the railway track and wait in the adjacent field. If it is beyond the wit of Humberside Police to send officers to ensure that area is clear, before directing away fans into an ambush, I wouldn't put any money on further arrests.
