An 11-month-old girl has died after being mauled by a dog, police have said.
Two people, a 24-year-old man and a 20-year-old woman, have been arrested on suspicion of child neglect and are in police custody.
The unnamed victim was taken to Royal Blackburn Hospital from a home in Emily Street at 11pm yesterday and later died.
The dog was seized from the address by Lancashire Police.
Officers are continuing to carry out inquiries at the scene and investigate the circumstances of the incident.
Detective Superintendent Simon Giles said: "This is a tragic incident and specially trained officers are offering support to the wider family.
"A full investigation is under way."
Police have yet to confirm the breed of dog involved.
The relationship between the baby and those arrested has not been confirmed.
It is believed the girl was not at her home address at the time of the incident.
Nobody else was injured during the attack.
