Police officers in Essex have drained a pond near the scene where Saudi Arabian student Nahid Almanea was murdered in Colchester last Tuesday and are carrying out an "intensive fingertip search."
The 31-year-old was stabbed 16 times and left to die as she walked along a quiet footpath in the town.
The search came as Detective chief superintendent Steve Worron issued a new appeal for information about a man seen wearing a "distinctive" beige-coloured jacket while walking along the Salary Brook Trail, where Ms Almanea was killed, around the time of the attack.
