Michael Boyd was also placed on the Sex Offenders’ Register for his antics, which included telling one terrified woman she had “nice boobs” and saying 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, was responsible for a series of creepy cab rides last summer.

He ogled female passengers and sat outside their homes after dropping them off, while other passengers believed he had been performing a sex act on himself shortly before they got into his vehicle.

Boyd admitted placing four women in a state of fear and alarm and lying to council bosses to get a taxi license when he appeared in court earlier this year. And, when he returned to the dock at Paisley Sheriff Court this week Sheriff David Pender jailed him for six months and placed him on the Sex Offenders’ Register for seven years.

Boyd picked up one of his victims — who can’t be named for legal reasons — from a party in Neilston at around 2.30am on June 28 last year.

After getting in his cab at around 2.30am she thought he was someone she knew and spoke to him.

Pamela Flynn, prosecuting, previously told the court: “He spoke to her like she knew him and didn’t correct her and then she realised he was not the person she thought.

“She was somewhat alarmed he hadn’t corrected her and was pretending to be someone he was not.

“He stated, ‘you’ve got nice boobs’. The witness was shocked and felt the comment was inappropriate.

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

“He repeated himself, asking why he couldn’t get a girlfriend.

“She noted the doors were locked and that he was driving on a back road and was not amongst a built-up area.” She was so scared for her safety that she texted and phoned her brother and got Boyd to go and pick up her boyfriend.

As he sped back to her home her boyfriend had to ask him to slow down and, when she arrived at her home in Barrhead, she was “shaken up and distressed”.

Exactly a week before he leered over another woman as he took her back to her Barrhead home after picking her up in Paisley, and in March last year he locked another victim in the back of his cab after picking her up in Glasgow city centre, ranting at her and quizzing her on why he was still single.

And in April last year he left a couple feeling uneasy after picking them up at a flat in Glasgow’s Dennistoun area to take them back to Paisley.

Flynn said: “Both witnesses were extremely concerned that the drivers’ seat was quite far back, to the extent that the girl in the back had to sit side on. They also noted the accused appeared to be really fidgety and nervous, pulling at his jacket.

“They formed the view that he had been masturbating in the vehicle shortly before they got in.” Boyd had been working as a taxi driver in his home town of Kilmarnock in 2013 but several women made complaints about his behaviour while they were in his cab.

He surrendered his license and then applied to East Renfrewshire Council for a license to drive taxis in and around the Glasgow area.

He lied to get the new license, saying he had never held a taxi drivers’ license before on his application form.

East Renfrewshire Council granted him a taxi driver’s license on April 7 last year and he began driving for Hampden Cabs, and the incidents began taking place just a few weeks later.

The six-month sentence will run alongside a stretch Boyd is already serving for similar antics in his home town.

Last month Sheriff Iona McDonald locked Boyd up for 15 months, reduced from 21 because he admitted his guilt.

He locked one of the Ayrshire women in his car, pestered her to go out with him and said he would keep her in his taxi until she gave him her phone number.

A matter of hours later he left another female passenger petrified as he took her back to her home from a friend’s house, telling his firm he hadn’t collected her and then repeatedly telling her he hated women during the journey.
