Dozens of angry protesters – some of them masked – confronted police after a march in support of Mohammed Yassar Yaqub, shot by police on the M62.
There were reports of confrontations and scores of drivers were held up around the town centre as around 70 protesters marched down Halifax Road and across the Ring Road, blocking traffic near Huddersfield Leisure Centre
Protesters headed for Huddersfield Police Station where about 20 officers arrived to keep order.
Angry protesters chanted: “Don’t shoot!” as they headed towards the police station.
Outside Mr Yaqub’s father Mohammed was seen speaking to police officers.
A witness told the Examiner protesters jumped on the car bonnets of passing motorists and one man had his ignition keys snatched.
“It was terrifying,” she said. “People don’t want this disruption and just want to get on with their lives.
“They are alienating the people of Huddersfield with these protests. The police have to deal with it.”
West Yorkshire Police have been asked for a comment.
