Married PC Gary Cryans, 51, was alleged to have carried out a number of assaults on three colleagues all in their 20s.
One claimed he assaulted her as she sat drunk in his car after a night out and tried to make her carry out a sex act on him.
Another said he tried to kiss her while the pair were parked up on a mobile patrol.
And the third alleged he pinned her down on a couch at a party and kissed her and touched her and made inappropriate comments while on shift together.
After a week-long trial at Glasgow Sheriff Court, Cryans was cleared of sexually assaulting the three women.
He faced seven charges and lodged special defences of consent for four claiming he was having an affair with one woman who featured on three of them, and that another had been the one to kiss him.
The court heard from the first woman who claimed it was easier to go along with what he said and did.
She denied they were in a relationship and told the jury she did not want him to do the things he did to her.
The second witness and police officer claimed Cryans made a move on her while they worked together.
The third officer told the court PC Cryans – who has 11 years police service – kissed her on a night out when they were alone then touched her leg.
She also alleged how at another party he pinned her to the couch and kissed her again.
She told the court how she was scared to report the incidents to anybody.
In evidence PC Cryans said he'd been having an affair with one of the women and everything that had happened was consensual. He also told the jury the second woman had kissed him on a night out. He claimed everything said by the women was lies and that it was made up to get him moved from the shift.
