Police are investigating the death of a young woman whose body was found in the early hours of this morning.

Paramedics were called to a flat in Leybourne Terrace, Stockton, just after 1am where they found the 20-year-old in a collapsed state. She was confirmed dead at the scene.

A post mortem was carried out yesterday but proved to be inconclusive. The results of toxicology tests are still unknown.

The woman, who has not yet been identified, has only just been released from prison. A man is currently being held in custody on suspicion of supplying her with heroin and was due to be questioned by police today. .
