A police cordon is in place and crime scene investigators are on the scene at an estate in Stockton.
Police have cordoned off the whole of Tilery Estate, in Norton, following an incident night overnight.
Much of Tilery Road and Tilery shops are behind police cordons, with the estate's residents unable to retrieve their cars without police help.
Crime Scene Investigators in hazmat suits descended on the estate around 5.30 am this morning to collect evidence, and uniformed officers remain in Norton this afternoon.
The police have been contacted for a statement. Officers are currently still at the scene and the cordon is still in place this afternoon.

A shop owner said: "Things like this happen here all the time but this time it is a little bit more shocking. It is not a good estate."
Groups of people are gathered near the tape, and a traffic warning has been put out, due to queues of slow-moving drivers wanting to see the scene of the incident.
A spokesperson for North East Ambulance Service "We received a call at 3.26am this morning (Friday 8 September) to reports of an incident at a private address in Stockton.
"We dispatched one ambulance crew and a clinical team leader to the scene. One patient was taken to hospital for further treatment."
The reason for the cordon is unknown with speculation circulating online, though Cleveland Police have yet to comment.
