Images of a man, connected with violent disorder in Darlington earlier this month, have been released as officers search for him.
Police want to identify the man after "sporadic pockets of violent disorder" erupted in Darlington two weeks ago.
Officers were deployed to the North Lodge Park area on the evening of Monday, August 5, after two large groups of mostly males gathered shortly after 9pm.
Durham Constabulary has asked anyone who may recognise the man in the images to get in touch.
A spokesperson for the force said: "If you can help, call us on 101, quoting crime reference number CRI00562188, or use the live chat function on our website.
"Information can also be submitted anonymously to Crimestoppers on 0800 555 111, or via their website at www.crimestoppers-org.uk."
