A man has died in a police shooting during a “pre-planned” operation near junction 24 of the M62 motorway in Huddersfield.

A West Yorkshire police spokesman said more than one arrest had been made and those held needed hospital treatment for injuries “not related to firearm discharge” after the operation at about 6pm on Monday.

No officers were injured, the spokesman said.

The dead man’s identity had not been released on Tuesday morning and police were yet to confirm any further details about the operation.

The force said it had informed the Independent Police Complaints Commission and was “fully co-operating” with the watchdog’s investigators.

Slip roads at the junction were closed while the scene was being examined.

A police spokesman said: “During a pre-planned policing operation near to the M62 in Huddersfield a police firearm was discharged and a man has died. The slip roads east and westbound at junction 24 of the M62 remain closed.

“An immediate referral has been made to the Independent Police Complaints Commission who are in attendance in West Yorkshire and West Yorkshire police are fully co-operating with their investigation.”

Witnesses reported seeing “five or six” police cars, a Mercedes E Class and a Jaguar at the scene.

Gemma Wilson, a local councillor, told Sky News: “I assumed at first it was a crash but realised if it was, it was a major one due to the volume of police in the area and the wide area that was cordoned off. It was obviously concerning to see so many police cars as clearly something serious had happened so close to home.”
