former Clyde 1 DJ Suzie McGuire's mum yesterday denied claims she was lying for her daughter in court.

Sheila Johnston, 70, said she saw a bite mark on her daughter's face on Christmas Day 2009.

She told Paisley Sheriff Court "it was a definite bite mark" and rejected the allegation she was "backing up" Miss McGuire.

A friend of the former drivetime presenter, Lisa Marie O'Donnell said she followed Ms McGuire's estranged husband Derek Mitchell last October 31 - days after he was granted bail - when she saw him driving behind Miss McGuire and heard that she was "terrified".

The women gave evidence at the court where Mitchell faces a string of charges including assaults and breaches of the peace between March 2009 and October 2013.

Under cross-examination by defence lawyer Billy Lavelle, Mrs Johnston said her daughter had a visible bite mark on Christmas day 2009.

He put to her: "I have to suggest to you Mrs Johnston that Susan McGuire, your daughter, never had a bite mark on her face.

The pensioner replied: "And I am telling you, as I said yesterday, it's as it was, that's exactly as it was.

"I can't say anything other than what I saw."

Call centre manager Mrs O'Donnell, 32, gave evidence that on October 31 last year - days after Mitchell had appeared in court over assault charges on Miss McGuire and was granted bail with special conditions not to approach or contact her - she helped Miss McGuire move belongings from her house in Eaglesham to a new house.

She said afterwards, as all three women were driving in their own cars between East Kilbride and Cambuslang, she saw Mitchell driving behind Miss McGuire.

She said: "I thought, 'he's following her, he's following Suzie, he's trying to get to her'."

She told the jury: "I was scared Suzie and my mum and anyone at my house would have been at risk."

The court also heard that between July and October last year, Mrs O'Donnell's mother, Ellen McHaghne took Miss McGuire and her children in because the presenter "didn't feel safe".

Mrs McHaghne told the court the former DJ stayed in a house that was attached to her house in Cambuslang for a few months.

Mitchell denies the charges.

The trial continues.
