POLICE have launched a murder inquiry after the bodies of two adults and two boys were found in a Leeds house.
Emergency services were called to a quiet cul-de-sac in Pudsey, late yesterday afternoon when the grim discovery was made in an upstairs bedroom.
Detectives are thought to be working on the theory that the deaths were a case of murder/suicide. No one else is being sought.
West Yorkshire Police said the bedroom where the bodies were found was fire-damaged.
The bodies were of two adults - a 37-year-old man and his 36-year-old female partner - and two boys aged nine and one.
Part of Sheridan Way where the house is located was initially cordoned off amid fears that dangerous chemicals might be present.
Detective Superintendent Paul Taylor of the West Yorkshire Police homicide and major inquiry team said: "Initially, we had concerns regarding the release of harmful chemicals or gases.
"Following testing, we no longer have any concerns with regards to those working at the scene and we will continue our investigations today.
"Inquiries are at an early stage and I would ask anyone with information about the incident to contact the homicide and major inquiry team."
Neighbours said the people who lived in the modern stone-built house were an ordinary family who had been there for only a few months.
One woman who laid flowers at the police cordon said her children went to school with one of the boys.
She said: "It’s terrible. From what I saw of them, they were very fun-loving, kind and caring - full of life."
The woman, who did not want to be named, said: "They were a nice family."
Police and scientific support officers were at the scene this morning.
The house, which has an integral garage, has a broken lounge window - the only other sign of anything out of the ordinary.
Family photos could be seen inside. Two cars were parked outside.
A police spokesman said officers were called to the house at about 5.30pm yesterday.
Neighbours all spoke of their shock.
One woman, who lives round the corner, said: "It’s such a shock. We’ve been up all night watching what’s been going on.
"This really is a quiet street. You just don’t expect it.
"I didn’t know them, apart from seeing them around and about.
"They had two boys. It’s just so sad."
The tragedy comes just days after a police officer who had been dismissed by his force attacked his family before apparently killing himself.
Toby Day is thought to have killed his primary school teacher wife Samantha and youngest daughter Genevieve, six, in a frenzied attack at their home just days after he was sacked by Leicestershire Police.
He also attacked their other children Kimberley, 15, and Adam, 13, before taking his own life at their home in Melton Mowbray, Leicestershire, on Thursday.
