Three children and a man have been found dead at a house in Surrey.
The tragic discovery was made shortly after 1pm today after paramedics called police to the property in Spelthorne.
Detectives investigating their deaths believe it to be an isolated incident, with no third-party involvement.
Their family has been informed and are being supported by specialist officers.
Chief Inspector Lucy Sanders said: ‘This is a tragic loss of life in our community and we are working to establish exactly what has occurred.
‘There is currently a significant police presence at the location, and in the surrounding area, and we would like to thank local residents for their patience and understanding whilst we conduct our investigation.’
Surrey Police have also completed a mandatory referral to the Independent Office for Police Conduct (IOPC) due to previous police contact with those involved.
An IOPC spokesperson said: ‘We have been notified by Surrey Police about the tragic incident in Spelthorne today.
‘We will be assessing a referral from the force to decide whether any action is required by the IOPC.’
