The police were called, independently of the School, and when they attend the School told the police that there were no CCTV images of the attack. Which is strange, because the school had already reviewed the CCTV and there was indeed images of the assault. When the police were informed of this (i.e. the school had lied about the CCTV) the police then asked for a copy the CCTV, but were refused, demanding the police obtain a warrant.
This school was given a near outstanding mark by OFSTED, but who would want their child to go to that school?
