Newcastle United fans clashed with police after their team was beaten 3-0 at home by Sunderland in a one-sided Premier League derby at St James' Park on Sunday (April 14).
Trouble started in Newcastle city centre on Sunday afternoon, Northumberland police tweeted as the situation unfolded.
"There have been pockets of disorder involving NUFC in Newcastle city centre. No major disruption, officers are on the scene and dealing with it," the police said.
"CCTV and evidence is being gathered and action will be taken against anyone involved in these sporadic incidents in Newcastle."
Local reports indicated that a flare was thrown by Newcastle fans at Sunderland supporters before kickoff and the Sunderland team bus was greeted by hostile hordes of Newcastle fans as it arrived at the ground.
The game started at noon and ended in a resounding victory for Sunderland, their first win at their rivals since 2000 and their biggest victory in Newcastle since 1966.
