A short film about a teenager who was groomed online through gaming and then murdered has been released as part of a new awareness campaign.
14-year old Breck Bednar was killed in Essex in 2014. Now his story is being shared by four police forces who are working together to promote online safety.
Essex, Northamptonshire, Leicestershire and Surrey police will now show the film to students at secondary schools in their force areas.
Breck was befriended by 18-year old Lewis Daynes, a predator who turned the 14-year old against his family and friends.
Despite grave concerns about their relationship, Breck's family couldn't stop what happened.
Daynes, who lived in Essex posed online as a successful computer entrepreneur.
He eventually lured Breck to his flat there and stabbed him to death. They'd never met before.
But online, while playing computer games, Daynes had convinced the teenager he was his true friend, the only person who had his best interests at heart.
After the murder Lewis Daynes dialled 999.
Brett's Last Game was showcased at a Northampton cinema.
Northamptonshire's Police and Crime Commissioner believes the film is money well invested.
The film will be initially shown in schools and colleges, helping young people to understand if they, or a friend, are being groomed.
