Detective Superintendent Gary Ridgway, of Cambridgeshire Constabulary, has paid tribute to the victims who gave evidence at the trial of a Peterborough sex gang.
Two men and two teens were convicted of a series of rapes and sexual assaults. A third teen was convicted of sexual activity with a child.
These girls were targeted simply because they were vulnerable. They were seen as easy targets and exploited by this group of teenage boys and young men who abused them for their own sexual gratification.
The victims, who were as young as 12 years old, were subjected to horrific ordeals. But they have shown incredible strength throughout this process: in particular by giving evidence at court in order to bring these people to justice.
