Four people arrested in connection with drug and robbery offences following an incident in Thetford have been released on bail.

The two men and two women, aged between 30 and 41, were arrested on Tuesday, December 13 on suspicion of supplying Class A drugs and robbery after they were found in possession of suspected stolen property.

The arrests were made in connection with the death of a woman at a property in Frobisher Close on Monday, December 12.

The woman, aged in her 40s, was pronounced dead at the scene by paramedics and while a Home Office post mortem examination proved inconclusive, it revealed no primary evidence of traumatic injuries and no evidence of third party involvement in her death. Officers will now prepare a file for the coroner.

All suspects were questioned at Wymondham Police Investigation Centre and have been released on bail until February 28 while enquiries continue.
