POLICE could have prevented an assault that left a man unconscious and needing surgery if they had responded to an initial 999 call, an investigation has found.

A woman was also nearly raped at the property before police officers arrived at the scene almost two hours after the alarm was first raised.

The male victim was seriously assaulted by his attacker at homeless accommodation in Penicuik, Midlothian, on three occasions between 2am and 3.02am on September 3, 2018.

He rang Police Scotland on 999 at 2am and 2.21am to report the first two assaults and was unconscious by the time the first officer arrived at 3.43am.

An investigation by the Police Investigations and Review Commissioner (Pirc) found the controller at Bilston Area Control Room (ACR) failed to prioritise the incident and sent officers to lower priority incidents. The report stated: “It is highly likely that had the ACR controller directed officers to attend the initial reported assaults then the later assault on the man would not have occurred.”

It found the victim was attacked after he refused to join in with a man who asked him to take part in the rape of a woman.

At 2am, the injured man rang Police Scotland on 999, stating he had been assaulted, was injured, needed medical attention and the person responsible was still there.

He dialled 999 again at 2.21am to report he had been assaulted again by the same man had a number of head injuries and was bleeding heavily. He was assaulted by the man for a third time at 3.02am.

At 3.24am, details of the incidents were brought to the attention of the local police sergeant who arrived at the scene at 3.43am, supported a short time later by other police officers. They found the injured man unconscious and with severe injuries, including facial injuries that required reconstructive surgery.

The Pirc report found that sometime, probably between the second assault and the third assault, the attacker forced entry to the woman’s locked room and tried to rape her. She resisted and managed to fight him off. Police found her in her room at 4.14am when she reported the attempted rape.

The report said: “During the course of these incidents, police officers in the area were directed to attend lower priority calls by Bilston ACR.

“No thought appears to have been given by the Bilston ACR controller to redeploying local officers or tasking resources in adjoining areas or in other business areas to attend the calls. Overall, the controller failed to prioritise this incident, control and direct resources appropriately.”

Investigators could not determine whether officers could have arrived in time to prevent the attempted rape if they had been sent to attend the initial reports of serious assault.

The man who carried out the assault was arrested and later stood trial at the High Court in Edinburgh where he was found guilty of assault to severe injury and permanent disfigurement and assault with attempt to rape on December 18, 2018.
