Police have launched a murder investigation into the death of a pregnant teacher found dead with her unborn child at their home in Glasgow as a hunt for her missing fiancé continues.

Marelle Sturrock, 35, was 29 weeks pregnant when she was discovered dead at the flat she shared with her fiance David Yates, 36, in Jura Street, Glasgow, on Tuesday morning.

Police Scotland Detective Superintendent Nicola Kilbane said: 'Her partner David Yates is wanted in connection with Marelle's death.

'At this time we have no information to suggest anyone else has been involved.'

Yates's white Seat Ateca was found at Mugdock Country Park, some eight miles north of the couple's property on Tuesday, sparking a major search.
