The police watchdog will investigate Devon and Cornwall Police over Plymouth gunman Jake Davison’s possession of a shotgun and shotgun certificate.
Davison, 22, shot and killed his 51-year-old mother Maxine Davison, also known as Maxine Chapman, at a house in Biddick Drive in the Keyham area of the city on Thursday evening.
He then went outside on to the street and shot dead Sophie Martyn, three, and her father Lee Martyn, 43, in an attack witnessed by horrified onlookers.
He then killed Stephen Washington, 59, in a nearby park, before shooting Kate Shepherd, 66, on Henderson Place. She later died at Derriford Hospital.
Plymouth gun rampage ‘without precedent’ – police
The Independent Office for Police Conduct (IOPC) has said it is looking into how Davison acquired a shotgun and a shotgun licence, after they were removed from him by police last December following an allegation of assault in September.
However, his firearm and licence were returned to him in early July this year – just a month before his deadly attack.
The IOPC said that the investigation follows a mandatory referral from Devon and Cornwall Police.
