A TWISTED brother and sister are facing jail after they were spotted having sex in a train station lift.
Richard Finlayson, 21, and sibling Kirsty, 18, romped in the elevator as they were filmed by CCTV cameras.
The shocking 15-minute clip showed them exiting the lift %E2%80%94 only to return a short time later to have sex AGAIN.
And as they left for a second time Richard gave Kirsty a %C2%A320 note.
The depraved pair were later arrested by police after a railway worker at Motherwell Station raised the alarm.
Last night a family friend said the revelations had left the pair's family "destroyed".
It came after Richard, of Carluke, Lanarkshire, and Kirsty of Lesmahagow, admitted having unlawful sexual intercourse in June last year.
Hamilton Sheriff Court heard how they left an 11-year-old boy who was with them on the platform during their illicit tryst.
Depute fiscal Amanda Gallagher said: "They both went into the lift and were seen having sexual intercourse on the CCTV.
"Both accused then exited the lift for a short period before returning and continuing having sexual intercourse. "Both accused then stood up and left the lift. At which point Mr Finlayson was seen giving his sister some money."
The court was told Kirsty Finlayson had admitted the sordid act to police.
But she denied she'd had sex for cash %E2%80%94 while Richard said he gave her the %C2%A320 "as a brother, not for payment".
Last night the family friend said: "We're devastated. I was sickened when I heard about it.
"Most of the family knew nothing about it until letters for the case came in.
"We can't believe it. It is a nightmare."
Sheriff Ray Small ordered Richard to be placed on the sex offenders' register. The brother and sister will be sentenced next month.
