A PORT Seton pensioner who pleaded guilty to exposing himself to two schoolboys and asking them to perform sex acts has carried on offending while awaiting sentencing.

Robert Cockburn, 75, had his trousers around his knees when the two boys entered a public toilet in Musselburgh earlier this year.

The OAP asked the shocked youngsters – aged 12 and 14 – to perform a sex act on him before they managed to flee the public convenience.

Cockburn also targeted two adult men by staring at them while they urinated within the same public toilet at the town’s Shorthope Street.

Cockburn appeared at Edinburgh Sheriff Court on October 12, where he admitted four offences, including breaching bail conditions banning him from the public toilet, and sentence was deferred for reports.

But just one week later, the pensioner was said to have exposed himself and performed a solo sex act in front of a 74-year-old man who was using a public toilet in Haddington.

Cockburn also made sexually explicit remarks to a 67-year-old man at the same location later the same day.

Edinburgh Sheriff Court was told that Cockburn then committed an act of indecency by lowering his clothing, exposing his buttocks and placing his hands near his genitals two days later near his home in Port Seton.

Cockburn was due to appear back in the dock for sentencing at the capital court today (Wednesday) but failed to show up and a warrant was issued for his arrest.

His name had previously been added to the sex offenders' register.

Last month, the court was told that police received several calls from members of the public reporting that Cockburn was watching men urinate within the public toilet at about noon on August 12 and 21.

Fiscal depute India McLean said that Cockburn, of Links View, Port Seton, asked one man to perform a sex act on him and, after he was arrested, the pensioner was bailed with the condition to keep away from the public toilets.

But over the course of the next week, Cockburn repeatedly flouted the bail order by turning up at the toilets and staring at adult men while they urinated.

Ms McLean said that the two schoolboys then “attended at the public toilets” and found Cockburn inside at about 5pm on August 27.

The fiscal depute said: “Mr Cockburn was within and had his trousers at his knees and his penis was exposed, and he asked the boys for oral sex.”

Police were called and, when Cockburn was arrested and charged, the court was told he denied any wrongdoing.

On Wednesday, Sheriff Roderick Flinn was told that Cockburn was admitting three new charges of exposing himself, making sexual comments to adult men and breaching bail conditions between October 19 and 21.

Solicitor Hannah Ridgway told the court that she had no explanation for her client’s absence and the sheriff ordered a non-appearance warrant to be granted.
