Nottinghamshire Police said Cameron Toner, 19, of Leicester, had been charged with three counts of common assault and a separate offence of going on to a playing area at a football match for his actions during Forest’s FA Cup win over the Premier League side.
Toner has been banned for life by Leicester, while earlier this month Rotherham gave two supporters lifetime bans after a pitch invasion where Harry Pell appeared to be struck as he prepared to take a penalty against Accrington.
“That’s a real concern and it’s never really been flagged before because most of the time, if you get a pitch invader, there’s a jovial atmosphere around how many stewards they can evade,” added Mousinho.
“Now there’s an aspect of violence which is really worrying. It’s really shocking and concerning. Hopefully it’s an isolated few weeks in an isolated season but it’s something we need to get on top of very quickly.”
