A grooming gang suspect who had escaped investigation because of a string of police failings went on to attempt to murder his wife, a Guardian investigation can reveal.

The man, named only as Offender J in paperwork seen by the Guardian, is alleged to have taken part in the gang–rape of 12-year-old Samantha Walker-Roberts in Oldham, Greater Manchester, in 2006.
