Specialist officers are investigating after a Blues fan allegedly invaded the pitch at their away game at the weekend.
Southend United's dedicated football officer said an investigation was launched on Saturday after video widely shared across social media reportedly showed a Blues fan being restrained during the match at Solihull Moors.
The video posted on on Twitter allegedly shows a Solihull Moors steward restraining a Southend United fan.
West Midlands Police has confirmed specialist officers are carrying out enquiries after an allegation of assault against a steward.
Officers are also investigating and reviewing footage after a fan from the away end allegedly invaded the pitch towards the end of the game and "pushed" a home player.
A West Midlands Police spokesman said: "We're carrying out enquiries and reviewing footage after a fan invaded the pitch at the Solihull Moors vs Southend United match on Saturday (August 13).
"A supporter from the away end encroached onto the pitch towards the end of the game and pushed a home player.
"A 20-year-old man was initially detained on suspicion of assault and going onto the playing area. He’s since been released and will be interviewed at a later date.
"We've also received a second allegation of assault against a steward and enquiries around this are also being undertaken.
"Specialist officers from both West Midlands Police and Essex Police are leading the investigation."
