The chief constable of Thames Valley Police has apologised for the delay in securing convictions against seven men who abused girls between 2004 and 2012.

Sara Thornton admitted that, despite complaints from victims, a joint investigation did not begin until 2011.

In one case in 2006, a 14-year-old told police she was one of a number of child victims but no action was taken after she withdrew her complaint.
