He added: “It is absolutely disgusting that someone would deliberately deface the memorials honouring the memories of PC Ian Broadhurst and Sgt John Speed, who were murdered in the line of duty and made the ultimate sacrifice while attempting to protect the public from armed and dangerous offenders.”
West Yorkshire Police said it was alerted to the damage on PC Broadhurst’s memorial on Saturday and believed it had been targeted between 18:10 to 18:20 GMT.
As well as paint being daubed on the stone, wreaths and flowers laid at the site had also been strewn about, the force said.
Police were then made aware of vandalism to the second memorial on Sunday morning and believe the damage occurred in the early hours.
Ch Supt Dodds said PC Broadhurst’s memorial had been cleaned and Sgt Speed’s would be similarly restored.
He added: “Thankfully we don’t expect there to be any lasting damage to either.”
