Storylines
Ken is married Sandra O'Brien in Sunderland and became stepfather to her two children Disa O'Brien and Ginny O'Brien. Unbeknown to Sandra, Ken sexually abused both her girls. Disa ran away from home to live rough on the streets of London, turning to prostitution to survive. However, Disa had fallen pregnant with Ken's child, and he followed her there.

Ken is first seen on-screen in December 1990, when Mark Fowler (Todd Carty) witnesses him harassing Disa and scares him away. Disa gives birth to Ken's daughter on Christmas Day 1990 in a derelict building. She abandons the baby – initially named Billie, later renamed Jasmine – on Diane Butcher's (Sophie Lawrence) doorstep, until Diane convinces her to stay in an empty flat in Walford, and helps her to bond with the child.

Ken traces Disa there in January 1991. He tricks Disa's childminder, Dot Cotton (June Brown), into letting him see the baby by pretending to be Disa's concerned uncle. He then kidnaps Jasmine. Ken wants Disa back under his control, but Dot, with police assistance, tricks him into meeting her, and leads him straight into the hands of the police. The baby is returned to Disa, and Ken is imprisoned.

With the possibility that Ken could be released, Disa is forced to admit to the sexual abuse he had subjected her to. Disa and her mother Sandra visit Ken in prison to confront him. Disgusted, Sandra informs Ken that she and her children will be testifying in court to ensure that he is imprisoned for a very long tim
