And we've got an official statement from West Yorkshire Police.

A police spokesman said that a man, age unknown, walked into Superdrug on Bank Street and was approached by staff in there on suspicion of theft.

He became aggressive and then left and headed into a bank on Market Street, believed to be NatWest where he was apprehended by a PCSO who removed him from the bank.

“He was still acting aggressively as he was removed and then assaulted the PCSO, who then called for emergency assistance,” the spokesman said.

“The man has been arrested on suspicion of theft and assaulting an officer and is currently in custody.”

The officer received minor injuries and it is understood no weapon was used.

"Witnesses report police arresting one man who was on the ground and struggling and he was led away."
