An investigation has been launched into Plymouth gunman Jake Davison’s possession of a shotgun and a firearms licence, which were returned to him in July after being removed at the end of last year.

Davison, 22, killed his mother on Thursday in the Keyham area of the city before going on to shoot dead four more people, including a three-year-old girl, and injure two others.
