A woman who was shot dead by police in Kent has been named by the Independent Police Complaints Commission (IPCC).
Part of the town centre was sealed off after the shooting
Ann Sanderson, 37, was shot in the car park of a department store in Sevenoaks after armed officers were called out to reports of a woman seen with a gun.
A post-mortem examination was being carried out on the victim, who lived locally, on Tuesday morning.
Ms Sanderson, who died on Monday, is thought to be the first woman shot dead by UK police for nearly 27 years.
The IPCC is leading the investigation into the shooting.
Witnesses described hearing a single gunshot at about 0300 BST.
School caretaker Kevin Taylor, 47, who lives near the car park, said: "There was a bit of shouting and stuff, and it was all over in about 20 minutes.
"A woman police officer was doing all the shouting.
"As soon as the shot rang out I knew it was serious.
"It was very, very loud - it sounded like a real meaty weapon."
Part of the town centre, including the bus station, was sealed off following the shooting.
Officers and forensic science experts have been searching the rear car park of the department store, which is based on Sevenoaks High Street.
A firearm was recovered at the scene, the IPCC said.
IPCC commissioner Nicola Williams said: "I send my sympathies to the woman's family and friends and also the police officers concerned.
"Whenever there is a fatal shooting by police our independent investigators go to the incident immediately."
Before Monday's shooting, teenager Gail Kinchin was the only woman ever to have been shot dead by police.
The 16-year-old was accidentally killed in 1980 by West Midlands police, while she was being held hostage.
