On February 20 he subjected a pregnant woman to a prolonged assault at a Ribble Valley hotel, leaving her with a bleed on the brain.
As a member of the public drove the victim away from the scene, 29-year-old Bamsey shouted that he would kill her.
When we spoke to the victim, she said Bamsey had subjected her to a number of previous assaults.
Bamsey was arrested and, following consultation with the Crown Prosecution Service, charged with assault occasioning actual bodily harm.
Bamsey, of no fixed address, appeared at Preston Crown Court last month where he was sentenced to six years in custody. An indefinite restraining order was also put in place.
