Twenty-one people have been jailed for child sexual exploitation offences in the last four years after a team was set up to protect vulnerable children.
The Sunrise team was launched by Rochdale Council after nine men were jailed in 2012 for grooming girls as young as 13.
Police and social workers working together helped more than 100 at-risk children last year.
They also target groomers and keep track of known offenders.
The council said it has visited over 600 premises in the borough and has closed nightclubs, takeaways and shops linked to child sexual exploitation.
