A MUM has told how she saved her daughter from six-year-old Alesha MacPhail’s murderer — only to end up in court accused of attacking him.

But she was stunned when cops charged her with assaulting the fiend, now 16, in Rothesay, Bute. Lyndsay, who was later cleared, said: “I think he was born evil.”

And Lyndsay revealed she thought the Scots killer was like Damien from horror film The Omen.

She was shocked when she saw the monster booting, punching and screaming obscenities at her hysterical girl, who like him was aged just 10 at the time.

But brazen Campbell tried to turn the tables on her by telling cops that she had laid into him.

His twisted lies led to Lyndsay being arrested, banged up in a cell and having to endure a court trial on an assault charge to clear her name.

And she admitted she wasn’t surprised that the beast, now 16, went on to commit one of Scotland’s most horrific crimes — the abduction, rape and murder of six-year-old Alesha MacPhail.

Lyndsay said: “From the moment I first saw Aaron when he was just two, I thought he was evil. He was like Damien from The Omen.

“I think he was born evil — his parents tried but he was always bad from the very beginning.

“He was a ticking timebomb and his conviction is no surprise.”

Lyndsay lived on Bute for years and became pals with Campbell’s mum Janette, 54, when the family moved to the island.

But the friendship came to an end following the disturbing assault on her daughter on August 31, 2012.

Lyndsay recalled: “We had been friends and neighbours for years.

“I considered Aaron’s parents Chris and Janette my best friends.

“This all happened when we were staying the night at their home because we were moving house and all our stuff was packed up.

“I was in the living room with his mum when I heard my daughter screaming in the hall.

“I went out and he was kicking and punching her.

“I separated them and told my daughter to go into another room.

“Then I tried to usher him through to his mum.

“But he started kicking me and then did a ‘spider’ and tried to stop himself getting put into the room.

“I didn’t assault him. I was just trying to get him away from my daughter and in with his mum.

“Then I said to them, ‘We’re not getting attacked by a 10-year-old, so we’re off’.”

FIRST FOR EXCLUSIVES THE Scottish Sun has led the way with our coverage of the story which shocked the country. We exclusively revealed how Alesha MacPhail’s teenage murderer was hooked on horror character Slender Man. On Saturday, we unmasked fiend Aaron Campbell after spearheading the legal battle to lift the ban on identifying him. And yesterday we revealed the last pic of Alesha at a pal’s party as distraught mum Georgina Lochrane, 24, paid tribute to her.

After Lyndsay returned home with her daughter, she asked about Campbell’s attack. And what she heard left her gobsmacked.

She continued: “She said to me, ‘He told me my face was like a vagina’. She was incredibly upset and I was stunned that a child would use language like that.

“Janette then started to send me texts claiming I’d attacked him, rather than the other way round.

“So I decided to head it off by going to the police at 2am and giving a statement.

“But Janette also went to the police and the next day I was arrested. I spent five hours in a cell before being charged with assault.

“I had that hanging over me for months before it went to a two-day trial at Greenock Sheriff Court.

“Aaron was so odd when he was giving evidence. He rocked backwards and forwards.

“He said I had kicked him in the scrotum and kicked him on the shins, which was a total lie. There were no marks on him.”

Lyndsay added: “He was simply not right. The sheriff cleared me after hearing the evidence.

“After that I had nothing to do with him or his family again.”

We told how Campbell crept into the MacPhails’ home — a five-minute walk from his house — and kidnapped Alesha from her bed.

He then subjected her to a sickening sex attack and smothered her last July. She was found naked with 117 injuries.

The teen was last week found guilty of abduction, rape and murder following a trial at the High Court in Glasgow.

His identity was revealed after judge Lord Matthews agreed with media lawyers he should be exposed.
