A man has been arrested on suspicion of manslaughter after an 83-year-old man mauled by a dog later died. He was taken to a west London police station and subsequently bailed pending further inquiries.

The man was attacked in the rear garden of his home in Rowan Road, Brentford by a pit-bull type dog which had escaped from a neighbour's garden. The dog caused bite lacerations to the victim's right leg and knocked him over, resulting in injuries to his left side and hand.

Three dogs have been seized from an address in Brentford. The victim attended West Middlesex Hospital for treatment and the matter was reported to police who attended the next day and recorded details of the incident but on Sunday 29 January, the victim was found dead in his home by his son. He has been formally identified as Leslie Trotman.

A special post-mortem examination has taken place at Fulham Mortuary and cause of death was found to have been haemorrhage resulting from a rupture to the spleen. Officers believe these injuries were sustained during the attack by the dog. The matter is now being treated as manslaughter, and the investigation has been taken on by the MPS Homicide & Serious Crime Command under Detective Chief Inspector Charles King.

Police are appealing to anyone who has any knowledge of the incident to contact them on 020 8721 4054 or Crimestoppers on 0800 555 111.
