A TEENAGER has relived the moment he was allegedly attacked by a police officer after he chapped the cop’s door as ‘a dare.’

The 15-year-old boy said he was chased in a car, nearly run over and then verbally berated before being set upon.

He told Paisley Sheriff Court he was left gasping for breath because of the alleged attack.

The boy was giving evidence at the trial of Detective Constable James Herbison, who denies carrying out the attack in Elderslie.

Prosecutors claim the 46-year-old officer restricted the child’s breathing after putting him on the ground.

DC Herbison faces a single charge of assault.

It is alleged that, on November 25, 2018, in Byres Road, Elderslie, he assaulted the boy by grabbing his clothes and using his own legs to pull him by the body.

The charge states that caused the youngster to fall to the ground, where DC Herbison pressed his knee against his body, causing his breathing to be restricted.

Giving evidence, the boy, who can’t be named for legal reasons, said he was attacked by a man after being dared to knock the door of a house.

He told the court: “He started shouting ‘What you chapping my door for? Don’t you ever chap my door again.’ He said ‘It’s not really funny, is it?’ and then he grabbed me.”

The boy, who was 14 at the time of the alleged attack, said he ended up on the ground, with the man on top of him.

He explained: “He put his knee on me really hard. I couldn’t breathe.”

The court was told a woman who spotted what was happening shouted at the man, who then got in his car and drove away.

It was stated the boy was able to tell police the man had been in a black Audi, as well as giving them part of the vehicle’s registration number.

DC Herbison maintains his innocence and the trial, before Sheriff Lindsey Kooner, was adjourned until later this month.
