Police chiefs are being urged to tackle reports of grooming more effectively after the murder of a teenage boy who was befriended online by his killer.
Breck Bednar, 14, from Surrey, was stabbed to death by Lewis Daynes, then 18, in his Essex flat in February 2014.
Weeks earlier, Breck's mother reported a change in his behaviour to police.
An Independent Police Complaints Commission (IPCC) inquiry found her call should have alerted officers to the possibility he was being groomed.
In January, computer engineer Daynes was sentenced to life in prison and told he must serve at least 25 years.
Chelmsford Crown Court heard how he lured Breck to his flat in Grays, Essex, after months of talking online on gaming websites and social media.
Mrs Justice Cox, sentencing, said she was sure the murder was "driven by sadistic or sexual motivation".
