A man has been arrested after four bodies were found in a house.
Derbyshire Police say they are not looking for anyone else.
Officers have not revealed what the man had been arrested for.
The bodies were in a house in Chandos Crescent, Killamarsh, near Sheffield.
The police had been called to the property.
A neighbour told Yorkshire Live:
“It’s a bit of a shock, it’s usually quiet round here so you don’t usually see police, not like this anyway.
Another added: “We’ve been away for 10 days and thought ‘oh god’ when I saw all of this.
“Police said ‘don’t worry’ to us but we don’t know anything.”
DCI Rob Routledge said:
“We would really like to hear from anyone who saw or heard anything suspicious in the early hours of this morning, or has any information which they think could help with our inquiries.
“No matter how small you think that information may be, please do get in touch with us.
“It is understandably a worrying time for the community, and we would like to thank them for their patience and understanding at this time.
“It was important to us that close relatives of those involved were informed before we could give further details about incident.
“Residents will continue to see a large police presence in the area, and patrols are being carried out for reassurance.
“If you do have any concerns, please don’t hesitate to speak to them.”
