Coronation Street star Tina O'Brien, who lives in an £1million home in a Manchester suburb, was involved in a scary situation right by her house. A spokesperson for Tina, best known for playing Sarah Platt on the ITV soap, told the Mirror: "Tina was the victim of an unprovoked incident outside her home which she has reported to the police." Tina became a star on Coronation Street when she was just 16 years old. She first appeared on the cobbled streets in 1999 and stayed until 2008.
