A taxi driver who locked female passengers in his car and made inappropriate sexual remarks to them during late night trips has been given a lengthy jail sentence.

Michael Boyd's behaviour included telling a woman passenger she had nice boobs and that he wanted to have sex with her after locking her in the back of his private hire vehicle.

The former Hampden Cabs driver made the comments to the woman while driving down a back road after pretending they were old friends.

The 34-year-old, who also worked for Compass Cars in Barrhead also stared at female passengers and sat outside their homes for as long as half an hour after dropping them off, while a couple he collected believed he had masterbating beforehand.

Boyd had earlier admitted at Paisley Sheriff Court to placing four women in a state of fear and alarm and lying to council bosses to get a taxi license.

On Tuesday, Sheriff David Pender jailed him for six months and placed him on the Sex Offenders' Register for seven years.

Boyd showed no emotion as he was told he was being jailed.

He picked up one of his victims from a party at around 2.30am in June last year.

She was so scared for her safety that she texted and phoned her brother and got Boyd to go and pick up her boyfriend.

Pamela Flynn, prosecuting, had told the court he was over familiar with the victim and he stated 'you've got nice boobs'.

"The accused carried on into comments about her being out of his league but he just wanted to have sex with her," she added.

Boyd is already serving 15 months in prison for similar offences.
