Police have released pictures of two men they wish to speak to in relation to disorders at the Millwall and Crystal Palace FA Cup tie on Saturday January 8.

Several objects, including a glass bottle, were thrown from the home stand onto the pitch at The Den, where the away side took a 2-1 win.

Inspector Matt Ashsted, from the Metropolitan Police Central Football Unit, said: “Sadly, a small minority are intent on causing trouble and resorting to violence. We are committed to identifying them and ensuring they face appropriate sanctions.”

“I would appeal to the public to come forward with any information that could help identify the two men.”

The match between the two south London rivals showed heightened levels of hostility off the pitch, where Millwall fans booed Crystal Palace players taking the knee before kick-off. Violence and discriminatory abuse led to five arrests.

The Football Association has been investigating discriminatory abuse the players faced throughout the match, including homophobic chants directed at Palace midfielder Conor Gallagher, on loan from Chelsea.

In a statement, Millwall’s CEO, Steve Kavanagh, said: “The club’s stance on discriminatory abuse of any form could not be clearer. There is zero-tolerance and any supporter found guilty will be banned from this club for life.”

Police have urged anyone with information regarding the two men in the images to contact 101, giving the reference 3200839/22.

Alternatively, anonymous information can be given to Crimestoppers on 0800555111.
