A killer involved in the fatal stabbing of a woman who aborted their baby has been sent back to jail.

Johnny Stirling was 15 when Nattalie Muir was knifed through the heart in December 2010.

He later admitted to his role in the killing and was locked up for six years after pleading guilty to culpable homicide.

Stirling, now 20, was released in March 2014 having served around half his sentence.

On Thursday, he returned to the High Court in Glasgow after admitting to attacking a young mother at a house in Mauchline, Ayrshire, in October 2015.

Stirling previously pled guilty to assault and abduction in connection with the incident at Ayr Sheriff Court.

Lord Matthews ordered Stirling to serve 279 days of the jail term he had been freed early from and told him he will be sentenced for the assault later in March.

Stirling was a teenager when Ms Muir was fatally stabbed in Whitburn, West Lothian, in December 2010.

He had "sworn revenge" on the 21-year-old after she became pregnant by him, but then had a termination.

Accomplice Emma Merrilees, then 20, struck the fatal blow. She was jailed for life after she pled guilty to murder.

George Stewart, 34 at the time, was locked up for more than eight years following his guilty plea to culpable homicide.

Lord Matthews, who previously sentenced Stirling for killing Ms Muir, told the high court hearing any new sentence will run at the end of the term he imposed.
