Two dogs that attacked and killed 68-year-old Esther Martin in Essex were XL bullies, police have confirmed.
She was visiting her grandson, 11, at a home in Jaywick, near Clacton-on-Sea, on Saturday when she was attacked.
Essex Police said post-mortem examinations carried out on the dogs, which were destroyed, confirmed they were XL bullies.
Ashley Warren, 39, was arrested on suspicion of dangerous dog offences and released on police bail until March.
Ms Martin’s daughter, Sonia, previously stated that her mother, from Woodford Green in north-east London, was told by the dogs’ owner to intervene with a broom when puppies in the house began fighting.
