A Londoner died after being attacked by his own dog while being interviewed for a documentary by a BBC film crew.
The Staffordshire bull terrier injured 41-year-old Mario Perivoitos in Wood Green on March 20, BBC said.
Neighbour Geoff Morgan, 52, told BBC: "I heard shouting - 'Get him off! Get him off me!'
"He was shouting really loudly. He was bleeding from his neck. There was a lot of blood."
A post-mortem gave the cause of death as "hypovolemic shock and damage to the airway consistent with a dog bite", police said.
The dog was seized and is in secure kennels, The Guardian reported.
A BBC spokesman said: "A crew making a BBC documentary were present - but not filming - at the time of the incident and called an ambulance.
"Given the ongoing inquiries, it would not be appropriate to comment further."
The BBC did not name the reporters or say what the documentary was about.
The breed is not banned under the Dangerous Dogs Act in Britain but in Singapore, it has to be leashed and securely muzzled when in a public place.
