Police have released images of three men wanted in connection with the Kill the Bill riot in Bristol on March 21.
Detectives leading the inquiry want to talk to Benjamin Broadribb, Dominic Gillett and Jacob Threlfall.
The men are among a number of people police want to identify after the protest against the Police and Crime Bill turned ugly. More than 70 people have already been arrested and four people have been jailed after the disorder.
All three men are in their twenties and likely to be in Bristol.
Avon and Somerset Police say Broadribb is likely to be in the city although he also has links to Glastonbury and Southampton.
He’s white, tall, of slim build and has long wavy brown hair.
Gillett is white, approximately 5ft 4ins tall and has medium length hair which is shaved at the sides.
He has a short beard and a scar on his forehead above his right eye. It’s believed he is in Bristol.
Threlfall is 5ft 5ins tall, of medium build with medium length hair. He is thought to speak with a Welsh accent.
A police statement read: “Police are urging anyone who know where the men might be to call 101 and tell the call handler you’re phoning in relation to Operation Harley.”
