Armed officers arrived shortly after 10pm on Monday and “took the difficult decision” to shoot and kill the dog, Met Police say.
Police officers shot and killed a “dangerously out of control” dog believed to be an XL bully after it injured four people in Battersea.
The dog began attacking people on Home Road at around 10pm on Monday evening, Met Police said, leading to four men being taken to hospital with non-life threatening injuries.
Witness footage of the incident shows one person throwing a blanket over the dog while another repeatedly hits it with what appears to be a helmet by the side of a car.
Armed officers arrived shortly after, police said, and “took the difficult decision” to shoot the dog.
A Met Police statement, which said the dog was “described as an XL bully”, added: “Officers subsequently arrested two people – a 22-year-old man and a 21-year-old woman – on suspicion of being the owner/person in charge of a dog dangerously out of control. Both remain in custody.
“Enquiries continue to establish the circumstances of the incident.”
The police added an examination of the dog will take place to confirm its breed.
One resident, who asked to remain anonymous, told Sky News: “There were four or five police cars and an ambulance.
“Someone was injured quite badly. It was very scary. It made us feel a bit unsafe as well.”
The resident said they later saw police officers covering the dog with what they thought was “aluminium foil”.
Another resident, who gave their name as Alex, said: “I heard genuinely the four loudest noises I’ve ever heard in my life.
