A police officer is set to face a misconduct hearing today for allegedly eating a kebab on duty and later failing to tackle rowdy behaviour in a pub.

Asked what he was doing in the period while eating the kebab, PC Richard Musgrave gave superiors the explanation that his earpiece had come out of his radio and his watch had stopped, it is alleged.

He then reportedly changed his story of what happened while he was on duty in March, Cambridgeshire to say he had fallen asleep.

'PC Musgrave was aware of the behaviour of the group and took no material or adequate steps to address it,' a report for a Cambridgeshire Police misconduct hearing said.

PC Musgrave then reportedly prepared a witness statement in relation to the incident which was 'incomplete, lacked detail, and contained assertions that were untrue'.

Several days later, PC Musgrave told a sergeant he had not been honest about his whereabouts on July 31, 2016, the report said.

'PC Musgrave then dishonestly told the sergeant that he had gone to the industrial estate to finish writing a statement and had fallen asleep there,' the report said. When challenged, PC Musgrave 'dishonestly told the sergeant that he had seen Ms A in town, had gone to pick her up, took her home and had something to eat there'.

PC Musgrave now faces a misconduct hearing starting today (Wednesday, January 3) at the Peterborough Education Conference Centre. It is alleged that the matters individually and/or collectively amount to gross misconduct.
