A paedophile teacher used his job at a primary school to sexually abuse six girls aged eight and nine.
And when one victim of Charles Ellis came forward to police in 2013, no prosecution was brought against him.
Instead he was given training about how to not touch children inappropriately at the Wirral school where he worked.
But his sickening abuse carried on for another three years.
The 60-year-old of Oakfield Drive, Upton, in Chester, was convicted of ten offences against six girls .
The victims were just eight and nine years old at the time.
Liverpool Crown Court heard how Ellis would put his hand on the girls' backs under their clothes, touch their bottoms under and over their clothes and touch their legs.
Charlotte Kenny, prosecuting, told how Ellis had been employed at the school, which the ECHO has chosen not to name, since 2002.
The offences spanned over eight years.
Ms Kenny claimed that Ellis was “motivated by sexual gratification” and “abused his position of trust” before more victims and a member of staff came forward to complain.
After his behaviour was reported by one of the victims, the police again became involved and revisited the earlier report about his behaviour.
A member of staff had also twice reported feeling uncomfortable about his touching some of the girl pupils.
He was suspended by the school in April 2017.
Miss Kenny told the jury that Ellis, who has no previous convictions, was “a man who appears not to be able to control himself.”
Judge Thomas Teague, QC, released Ellis on bail to enable a pre-sentence report to be prepared but warned him that he was likely to receive a custodial sentence when he returns on December 19.
