A SERIAL sex offender is facing an extra stint behind bars after two more victims bravely came forward.

Alexander Morgan, 72, preyed on the then young girls, who were aged 11 and 12 when he first struck, between 1992 and 1996 at addresses in Paisley and Blantyre.

The pervert was found guilty of two charges of lewd and libidinous conduct following a trial at the High Court in Glasgow.

After the verdict, prosecutor Liam Ewing QC revealed how Morgan is already serving a 10-year sentence for sex offences imposed in 2015.

This included the rape of a young girl in Paisley.

Mr Ewing added: "The report of these (latest) offences occurred after the imposition of the 2015 incidents."

Simon Gilbride, defending, said Morgan's earliest estimated date of release had been November this year before this case.

Lord Richardson deferred sentencing until next month for reports.
