Police are continuing to appeal for information following a shooting incident in Keyham, Plymouth, which left six people dead.

An online page has been launched and anyone who may be able to help the investigation, who has not already spoken with officers, is being urged to come forward.

A spokesperson for Devon and Cornwall Police said: "It offers an easy way for members of the public to report information direct to us.

"Enquiries are continuing at the scene and cordons remain in place. These will be closed gradually when appropriate.

"Post-mortems are taking place and will continue into early next week.

"Families of the victims are being supported by specialist officers and we ask that their privacy is respected during this difficult time."

Jake Davison shot his 51-year-old mother Maxine Davison, also known as Maxine Chapman, at a house in Biddick Drive before he went into the street and shot dead Sophie Martyn, aged three, and her father Lee Martyn, aged 43.

He killed Stephen Washington, 59, in a nearby park before shooting Kate Shepherd, 66, on Henderson Place. She later died at Derriford Hospital.

A 53-year-old woman and a 33-year-old man, who were injured during the incident on Thursday, are recovering in hospital with non-life-threatening injuries.

The circumstances surrounding Jake Davison’s shotgun certificate, and any information Devon and Cornwall Police had relating to him, are now the subject of an investigation by the Independent Office for Police Conduct (IOPC).
