Reports on a fans’ forum stated the Black Cats supporter - whose team have not won at home for almost a year - pulled down his pants and used his seat as a toilet during the 3-1 defeat to Reading.

A photograph of the teenager with his pants down in front of fans went viral on social media.

A Northumbria Police spokeswoman said: "Further to media reports reporting a fan defecated on his seat during the Sunderland v Reading match on Saturday, police would like to clarify that this was not the case."

The force revealed the 17-year-old was arrested for being drunk in a sports ground and "had been dealt with appropriately". 

The spokeswoman added: "At no point did he defecate on his seat."

A club spokesman said yesterday that the matter was in the hands of Northumbria Police.

The accused teenager has apologised for his actions. 

“There's no excuse for my actions,” he wrote on Facebook.

“That was me it's real I'm so regretful but I can't remember any of it at all and for the record I didn't actually have a ****."

He added: “I honestly didn't have a ****. The club even released a statement saying there was nothing wrong with the chair.”

Sunderland have not won at home since beating Watford in the Premier League in December 2016.

The Black Cats have since sunk to the Championship relegation zone.

They have picked up just two wins this term - both away from the Stadium of Light - and are in danger of dropping into League One.
