Adults worried about children getting involved in gangs should call the the NSPCC’s helpline, the charity has urged.
It says it has trained counsellors to deal with calls from concerned parents, after receiving Home Office funding.
According to the NSPCC, one in six children aged 13-15 knows someone in a gang. Bradford and Leeds have been listed among cities with major gang problems.
The charity says adults have “an incredibly important role” in allowing young people to escape.
Those who have concerns about a child or want advice can contact the NSPCC free by calling 0808 800 5000 - in operation 24 hours a day.
The project, part of the Government’s Ending Gang and Youth Violence programme, would “empower parents”, Home Office minister Norman Baker said.
