AN accountant who hounded his brother-in-law that had an affair with his other sister was admonished on Tuesday.

Martin O’Hara’s sister Kathleen McVey is married to 37-year-old personal trainer Patrick McVey.

Patrick had a three year fling with O’Hara and Kathleen’s younger sister Emma O’Hara.

Patrick eventually confessed to the adultery and later returned to the family home.

But, he was then targeted by the women's brother O'Hara.

O'Hara, 35, embarked on what was a described as a "toxic smear campaign" against the fitness instructor.

Over months, he repeatedly turned up at the house in Glasgow's Shawlands leading to the couple fitting electric gates to try and keep him out.

Kathleen, 33, was forced to block him on social media after being left physically sick by her brother.

O'Hara even turned his attentions to McVey's pensioner mum - approaching her in a park and also sending her an "unwelcome" message on Facebook.

The story emerged as the chartered accountant stood trial at Glasgow Sheriff Court.

He was found guilty in February of stalking Patrick, his sister Kathleen and the trainer's mum Margaret McVey, 69, between March 1 2020 and January 5 2021.

Sheriff Kevin McCarron ordered O’Hara to be of good behaviour for six months.

It was confirmed in a hearing that O’Hara had a positive good behaviour report and was admonished of the charge.

The trial heard how Patrick started an affair with sister-in-law Emma, then aged 22, in late 2016.

The fling ended in January 2020 when he admitted to his wife what was going on.

He left the family home before reconciling with Kathleen stating he was "extremely lucky" their marriage continued.

It was then shortly after that O'Hara targeted McVey and his sister.

Fiscal Darren Harty asked McVey about an early incident in June 2020.

The trainer said: "He came to the door and Kathleen made it clear that she did not want him to come round causing a lot of stress.

"He stated that he did not want to see or hear from me."

But, the hassling continued as McVey told the trial: "There were occasions where Kathleen would receive a message and she would vomit in a state of shock.

"She tried to explain this to her parents that any time she got a message from him her heart would start to race."

O'Hara later showed up again, insisted he was not leaving and only stormed up when he was threatened with the police.

The court heard the McVeys eventually erected electric gates at their home.

Patrick told fiscal Mr Harty: "Kathleen did not feel secure. It was due to the number of visits she was receiving that she did not know what else to do.

"It did not matter what she said or did."

Patrick also told how O'Hara phoned one of his friends and started mouthing off about the fitness instructor.

The call was recorded on the advice of the police.

Patrick said: "He was just making accusations about me saying I had other affairs - he said I was a big p****."

Kathleen also gave evidence against her brother and said he had helped create "a dangerous false narrative" about her husband after his affair.

She spoke of having to confront the "toxicity" of what was being said about Patrick.

Kathleen: "It was so sad this was happening, I was dealing with what they had done on top of that and then this smear campaign was happening."

Kathleen said her brother claimed Patrick was "sinister".

She recalled stating to her brother "lots of times" not to get in touch.

Margaret McVey meantime was in Newlands Park in the city's southside with a relative when O'Hara suddenly appeared stating: "Good evening, ladies."

He was also said to have accused the pensioner of being "controlling" by allegedly stopping him see Kathleen.

Margaret recalled: "I said I was not in charge of his sister."

Margaret also mentioned a later matter in January 2020 when O'Hara approached her in the street.

The worried had to cross the road to get away and sought the help of an elderly couple.

O'Hara meantime started shouting about Patrick's affair.

O'Hara in his evidence rebuffed claims by Kathleen that he had told business clients about the affair as he does not "support gossip."

Mr Harty stated: "You told two strangers in the street they were having an affair, did you tell anyone else about the affair or do you say that is not true?"

O'Hara: "I discussed there had been an affair with people but I did not get into the gory details."

O'Hara claimed he was not asked by Kathleen not to contact her but she wanted him to tell the family that Emma was a liar.

He added that it was not his intention to cause Margaret to be upset.
