A PERVERT followed a lonely teenager at night for 12 minutes before sexually assaulted her in a secluded car park.

Brian Ross 33, pounced on the 17 year-old at Glasgow Caledonian University in January this year.

The student was walking home to her accommodation from a night out when Ross leapt out at her.

Glasgow Sheriff Court heard Ross initially walked past the teen on a set of stairs before doubling back.

Ross fled the scene as the “distressed” victim shouted “What the f***.”

A 999 call was made which prompted a CCTV investigation by the police.

The court was told Ross’ Ford Focus pulled up at the city’s St Vincent Street just before three in the morning.

Prosecutor Mark Allan said: “Ross got out the car and walked to the side behind the witness and can be seen watching her as she appears oblivious to his presence.”

Ross could be seen following the teen for 12 minutes before committing the assault and fleeing the scene.

Moments later, Ross is witnessed returning to his car and driving out of view of the cameras.

Ross was traced through his car documents and he was arrested before initially denying his involvement when quizzed.

The court heard he later made full admissions and told officers he wanted to speak to the teenager who was on her phone.

Mr Allan added: “He was unable to say why he committed the assault or why he was in the city centre on his own in his vehicle in the early hours of the morning.”

Ross pleaded guilty today to the sexual assault.

Mr Allan informed the court that Ross’ last conviction was of a similar nature.

He said: “It involved him driving and loitering around Strathclyde University exiting his vehicle to follow lone females on foot.”

Sentence was deferred until next month for background reports by Sheriff Ian Fleming who remanded Ross in custody meantime.
