Police have cordoned off a road in Chelmsford while they conduct an investigation into an "incident".
At least three police vehicles are at West Avenue in Melbourne.
The Kings Road end of the street is blocked by a police car, while police tape is stretched across the other end at the junction with Langton Avenue.
Officers said that they believed forensics officers that could be seen inside the cordon would be at the scene until around 3 or 4am.
Police would only confirm that they were investigating an "on-going incident".
