A teenager was asked to expose himself to an ex-SNP councillor to receive free alcohol, a trial heard today.

The man claimed he was 17 when he was offered booze by Mark Kerr, 40, at a quarry near Croy, North Lanarkshire, in 2014.

He stated that Kerr had earlier offered him and a friend free cigarettes in exchange for a kiss. 

The man further stated to a jury that Kerr groped him while lying in a bed at a property in Croy. 

Kerr is on trial at the High Court in Glasgow accused of two charges of sexually assaulting the man.

The court heard that the man knew Kerr who worked at the local shop at the time.

The man stated that Kerr would supply him and his friend cigarettes, at times for free.

He said: “Mark Kerr wanted something more, he wanted us to kiss him.”

The man said his friend did kiss Kerr.

The man recalled a later time in 2014 when he and two friends joined Kerr to drink alcohol at the quarry.

He stated that Kerr supplied four bottles of VK alcopops.

Advocate depute Simon Gilbride asked if Kerr asked him to do something.

He replied: “Yes, he told me to get my c*** out.”

The man stated he initially refused but agreed if his friends looked away.

The witness claimed the four went back to his house where Kerr allegedly told him to run about his garden naked to receive free cigarettes.

He stated that he did so and felt “embarrassed”.

The man stated that he fell asleep on a mattress beside Kerr that night.

Mr Gilbride asked if anything caused him concern that night. 

He stated “yes” and that Kerr groped him.

The man said the incident lasted 10 to 20 seconds before Kerr left, stating: “I should probably go.” 

David Taylor, defending, put it to the witness that the man was dared by other friends, and not Kerr, to run about the garden exposed.

He replied: “I was dared to run about the garden in exchange for cigarettes.”

Jurors earlier watched footage of a police interview another man gave in July 2020.

He claimed that he was touched twice on the leg when he was “about 17” by Kerr in a tent near a canal in Croy. 

The witness stated that Kerr organised the camping trip as well as bought him and a friend alcohol.

The man claimed he fell asleep after getting drunk and woke up to being touched by Kerr’s palm.

He said: “The three of us were lying down in the tent and I was lying on my side while I was wearing jeans.

“I could feel the other man’s hand going down the legs of my jeans.

“I pushed his arms out the road and said ‘bolt - out the road’.

“I can’t remember anything after that. I felt him rubbing his hand on my leg.”

The man stated that he was rubbed twice by Kerr with “15 to 20 minutes” between both incidents. 

He added that Kerr went “towards my pelvic bone”.

He said he batted Kerr away, who touched him on the leg again 15 to 20 minutes later. 

The officer asked the impact of the incident on him.

He replied: “It was like a train hit me times two. 

“I try not to think about it - I try not to recall it.”

Kerr, now of Wishaw, denies a total of 14 charges involving six males between 2010 and 2020.

Charges include the rape of a man and an attempted rape of a teenager. 

The trial, before Judge Douglas Brown, continues.
