A grandfather is facing jail after trying to coerce two females to do the toilet in the back of his black hack taxi.

Pervert Robert Smith, 56, told the women during taxi journeys in April and June last year that he would waive their fare if they did.

Both women reported the incidents to the police and picked Smith, from Baillieston, Glasgow, out of a number of images shown to them.

After a trial at Glasgow Sheriff Court, Smith was convicted of repeatedly attempting to coerce one woman to urinate in the taxi, and another charge of coercing the second girl into removing her lower clothing and attempting to.

Smith - a father and grandfather - claimed the women did the toilet, he didn’t ask them to and was left with the mess.

The first women told the court that if she let him watch her that he would give her the taxi journey for free.

The second female, also claimed that while driving, Smith told her she wouldn’t need to pay if she did the toilet.

Sheriff Joan Kerr deferred the matter until next month, continued Smith’s bail and told him he was on the Sex Offenders’ register.
