A father has killed his wife and twin daughters at their home before taking his own life in a tragic triple murder suicide.
Pullarkattil Rethishkumar, 44, is thought to have smothered wife Shighi, and 13-year-old twins Niya and Neha, before travelling to a reservoir in east London where he hanged himself.
Officers attended a house in Grove Road in Chadwell Heath, on Monday evening after concerns were raised about the welfare of the residents there, but as there was no response and no sign of any disturbance they left.
However police returned to the house on Tuesday lunchtime and after forcing their way in, found the bodies of Mrs Rethishkumar and her two teenage daughters.
They began an immediate search for Mr Rethishkumar and on Wednesday morning found a body in undergrowth close to Woodford Reservoir in Walthamstow, north east London.
Detectives from Scotland Yard’s Homicide and Major Crime Command have launched an investigation into the deaths, but have confirmed they are not looking for anyone else in connection with the incident.
The last confirmed sighting of the family was on Sunday, Scotland Yard said.
The police response is now under investigation by Scotland Yard’s Directorate of Professional Standards and the matter has also been referred to the Independent Police Complaints Commission (IPCC) over concerns officers could have done more to prevent the tragedy when they first visited the property.
Friends and neighbours described the Rethishkumars, who are thought to be originally from India, as a “lovely” and “quiet family” who always appeared very close to one another.
Mother-of-two Zoya Habibani, 24, lives in the same block as the family and described them as "really friendly", adding: "It's really sad."
She said she thought the family were originally from India.
She described the incident as "really shocking" and said she did not want to tell her children what has happened.
"It's a really nice area," she added.
Samantha Puholy, 45, has lived in the area for 10 years, and said it is "very quiet".
She said residents would be shocked at the incident.
"It's very, very sad," she said.
Bobby Singh, 41, manager at the garage beside the block of flats, said he would see the twins going to school in the mornings.
He described them as "very reserved" and "polite" and said they have lived in the block for a couple of years.
But he said he did not see their father very much.
"The kids always walked in front of their mother. The mother was always a couple of steps behind," he said.
Mr Singh said he asked one of the police officers what had happened and he said as soon as they mentioned twins he knew it was them as there are not many twins in the area.
"I hope someone finds out the answers," he said. "I hope they rest in peace as well."
