Brentford deaths: Boy, 3, and his mother found dead in flat

Poorna Kaameshwari Sivaraj, 36, and her son Kailash Kuha Raj were last seen on 21 September

A three-year-old boy and his parents have died at a flat in west London.

The bodies of Poorna Kaameshwari Sivaraj, 36, and son Kailash Kuha Raj were found at Golden Mile House on Clayponds Lane, Brentford.

Scotland Yard said it believed both had been dead for some time. They were last seen on 21 September.

It is thought Kuha Raj Sithamparanathan, Kalish's father and Ms Sivaraj's husband, fatally injured himself when officers forced entry.

The 42-year-old was found with stab injuries and pronounced dead by paramedics at the scene.

The family's deaths mean London has recorded 100 violent deaths this year.

Police remain at the scene in Clayponds Lane, Brentford

Scotland Yard said officers initially received a phone call on Sunday from a family member raising concerns about the welfare of Ms Sivaraj.

Officers attended the address several times early on Monday but did not receive a reply.

Concerns heightened after speaking to neighbours and officers decided to force entry just after midnight on Tuesday.

A mandatory referral has been made to the Independent Office for Police Conduct.

Next of kin have been informed and post-mortem examinations are set to take place on Thursday.

Lead investigator, Det Ch Insp Simon Harding, said it was being treated as a murder investigation.

"We know the family often walked their dog, a poodle cross breed, in and around the local area and I would ask anyone who saw them at any time in the last month to contact police so we can begin to build a full picture of their lives," he added.

Officers were called to the property after receiving concerned calls from neighbours

West Area BCU Commander, Peter Gardner said: "This horrific incident has understandably caused enormous shock and concern among local residents and across the borough. All our thoughts are with the family and friends of those affected.

"Local residents can expect to see officers at the scene and patrolling the local area to provide reassurance, and if they have any concerns, I would urge them to speak to our officers."

'Very friendly'

Neighbours earlier told of their shock after the deaths of the family of three.

Sheri Diba said the family were "very friendly" and she used to regularly see them taking their dog for walks.

"I've always seen them in the lift. They were very friendly. They said 'Hi, how are you?' I always saw them together going for walks.

"I feel really bad (hearing the news) because they were very friendly, nice people."

Ms Diba, a mother of one, said she had lived in the building for seven years and described it as a "nice area", but said she had not seen the family for a number of months.
