A man who raped two women, violently attacked another female while he was out on early release from prison.
Fraser Summers, 30, was jailed for nine years in 2010 for raping two prostitutes in separate attacks in November 2007 and April 2008.
But after being released early he attacked Lauren Cusick and her friend Glen Faulkner, last April 16.
He grabbed Miss Cusick and strangled her against a shop window before chasing Mr Faulkner.
Summers then resisted arrest by refusing to allow officers to handcuff him, forcing a number officers to put him in the back of a van.
Summers, from Robroyston, Glasgow, went on trial at the city’s sheriff court where he denied assaulting anybody and claimed he was the victim of threats and was spat on during the early-morning incident.
But sheriff Eric Brown rejected his version of events, branding him “wholly incredible” and found him guilty of behaving in a threatening or abusive manner, two assault charges and resisting arrest.
Summers claimed he left the Savoy nightclub with his brother and insults and threats were hurled at him by a group outside McDonalds on Sauchiehall Street.
He alleged he was spat at by one of the group and was then taken a hold of by two police officers from behind who wouldn’t listen to him when he claimed he had done nothing wrong.
The court heard from Miss Cusick and her friends who described Summers making an “obscene gesture” by sticking his finger, or fingers up at them and acting aggressively.
Miss Cusick told how she was “terrified” when Summers grabbed her and held her by the neck against the window the EE phone shop.
He squeezed her neck, which stopped her from breathing or talking and punched her face.
She went to hospital and was given painkillers but took around three or four weeks off of her work after the attack.
Mr Faulkner described being “taken aback” by Summers’ who turned on him.
He said it was a “scary situation”.
Summers was recalled to custody to serve the remaining part of his High Court sentence.
Sentence was deferred on the current case until next month for reports.
During his rape trial Summers had accepted that he had attacked the women, but claimed that any sexual activity was consensual and denied the rapes.
The court heard that he attacked his first victim in November 2007 at ground in the Broomielaw area of Glasgow.
He approached the 37-year-old for sex before subjecting her to a brutal assault.
The victim was hit and slapped, dragged by the hair, thrown onto a pile of bricks and stones and had gravel forced into her mouth.
She eventually managed to run onto the street and stopped a taxi for help.
Summers struck again in April 2008 on waste ground at Carrick Street when he raped a second woman.
The 28-year-old was thrown to the ground and pinned down and called abusive names.
Summers was also convicted of punching two women at the Tunnel nightclub in Glasgow in November 2008.
