A man has been arrested on suspicion of murder after two women were found dead in a village in West Sussex.
Emergency services were called to a house on Hazel Way, Crawley Down, on Sunday morning and found the two women outside and a man seriously injured inside.
Sussex Police said it was an isolated incident with no further risk to the public.
The force gave no further details about the arrested man or the cause of death.
The injured man has been taken to Royal Sussex County Hospital in Brighton.
In response to reports that a knife had been involved, Detective Chief Inspector Alex Geldart, of the Sussex and Surrey major crime team, said: "I wish to make it absolutely clear that this is not a knife crime."
She added: "At this time we believe this to be an isolated incident, with no ongoing risk to members of the public.
"This is a fast-moving investigation which will see significant police resources deployed to the scene for the forseeable future.
"We are grateful for the support and patience of the local community while we conduct our enquiries."
Three forensic tents were pitched in the street, while residents said 10 police cars had initially been dispatched to the scene to deal with the incident.
Investigators in white forensic suits could be seen combing the area for evidence.
A police cordon remains in place around the houses close to where the bodies were found.
