Emergency Services are involved in a large scale emergency incident in Stockton.

The public should not be concerned because it is only a test.

Last Year Cleveland Police carried out a similar exercise to put the emergency services to the test in Hartlepool.

Police have reassured members of the public that there will be no impact on transport and there is nothing to be concerned about.

The exercise is a multi agency operation between Stockton Council, North East Ambulance service, Cleveland Fire Brigade among many others.

Once the exercise is underway members of the public will be able to know the exact location by following everything on social media.

Police Hour will have live updates throughout the day.
