Images of 12 men have been released over objects thrown during last month’s Merseyside derby.
A number of projectiles were launched onto the pitch at Anfield in the December 2 game, which Liverpool won courtesy of a last-minute goal from Divock Origi.
Detectives have released CCTV stills of people they would like to speak to and have urged anyone who knows them, or the men themselves, to come forward.
Match commander Superintendent Paul White said: “Following the match on December 2nd officers have been carrying out numerous enquiries and as such we have issued CCTV images of 12 males who we believe could assist with an ongoing investigation.”
