A picture of a man making an alleged racist gesture at a football match has been released by police.
Northumbria Police said there had been reports of a home fan gesturing in the direction of Tottenham supporters at Sunday's Premier League game with Newcastle United at St James' Park.
The force asked anyone who recognised the man to contact police.
Supt Jamie Pitt said: "We do not tolerate hate crime of any kind within our communities."
"While I know that this image has already been circulated widely across social media, I would ask the public to work with us and take a close look at the man pictured," he said.
