It was a violent and unprovoked attack that left a young woman undergoing surgery to rebuild her skull - and 18 months on, police are still searching for the person who did it. Suzanne Ratajova was walking home when a man on a bike rode up to her and punched her three times in the head.
The vicious attack was caught on CCTV and her emergency treatment filmed by a team making a documentary. Please be aware that Nick Thatcher's report contains disturbing footage from the start.
