A boy has died after being bitten by a dog.
The incident happened at a property in a residential street in Halstead, Essex, at 5.40pm on Thursday.
A 29-year-old woman has been arrested for allowing a dog to be dangerously out of control and injuring a person, Essex Police said.
The dog has been seized by police and placed in kennels.
The incident happened in Parker Way.
The boy was taken to hospital but died from his injuries, police said.
It comes just days after a 52-year-old man was attacked and killed by a dog which had been returned to its owner despite concerns that it was dangerous.
David Ellam was out walking with his Yorkshire terrier close to his home in Huddersfield on Monday when he was attacked by another dog. He later died in hospital.
West Yorkshire Police said the animal had been seized by police following a visit by a dog warden in June, but had been returned to its owner on August 8 after it was determined that it was not a banned breed.
The Independent Police Complaints Commission (IPCC) has said it will launch an investigation into Monday's attack.
