THE man who accused police officers of using their sirens and flashing lights to deliver coffee to a colleague has criticised delays into an investigation.

Gordon McIntosh made a complaint after claiming he saw the driver of a police car using emergency procedures – known as blues and twos – before taking the hot drink to another officer standing outside Islington Police Station in Tolpuddle Street, Angel, on August 27.

Mr McIntosh said he had seen what unfolded because he had been cycling behind when the siren and lights went on.

He said: “I asked the sergeant, who was joined by a constable, why he had used emergency procedures to deliver a coffee. He told me that they were en route to a murder.”

While the incident was referred to the Professional Standards Unit (PSU) in early September, Mr McIntosh said he feels it had now been “kicked into the long grass” as two months later there has been no movement on the inquiry into what happened.

An email to Mr McIntosh on October 3 by the investigating officer suggested the lack of “significant updates” could be explained by her focus on other cases, stating: “Please note I do have a number of other cases I am working on.”

A further email, dated October 31, said: “I continue working on this investigation alongside a number of other cases. I will however keep you updated with the progress every 28 days.”

Mr McIntosh said: “The excuse of being busy is annoying. It begs the question if there are so many internal investigations regarding potential malpractice why the department investigating is not more adequately resourced.”

Police have said they are looking at CCTV but Mr McIntosh said a simple check of who was working that day would be enough.

“Why would a memo to them asking them to come forward not have been the method of identification?” he said.

A police spokeswoman advised that CCTV was gathered as part of a wider investigation into what happened, rather than for identification purposes, but declined to comment further.

The Met confirmed in September that it was examining the circumstances through its Central North Professional Standards Unit.
