Two people have been arrested by police investigating the murder of a teenager in Norwich.

The pair - a man and a woman both in their 50s - were arrested in the Norwich area on suspicion of conspiracy to murder.

It follows the discovery of the body of a 19-year-old man in a ground-floor flat in Lefroy Road, on the Mile Cross estate, at around 10.40pm on Saturday.

Officers say the body of the victim, who died from a single stab wound to the chest, lay undiscovered for eight days.

They believe the murder was drug-related.
