A former Three Rivers teacher has been found guilty of a historic indecent assault on a teenage pupil.

Anthony John Pryor, 73 of Pinner, Middlesex was found guilty of one count of indecent assault on a girl under 16 years of age on Friday November 11 after a four-day trial at Isleworth Crown Court.

The offence happened in the early 1990s when Pryor was employed as a maths teacher at Northwood School, on Pinner Road, and the victim was a pupil aged 15.

A former pupil who knew the victim told the Observer: “The sentence was what she was expecting. I think she is just glad that it is all over more than anything else.

“Something about him made us uncomfortable. He tried to be friends with his pupils but we always thought he was smarmy.”

Pryor was sentenced to six months imprisonment suspended for 18 months. He will also have to sign the Sex Offenders Register for seven years and has been ordered to pay costs of £1,200.

The allegation was reported to police in 2014 and an investigation began by officers from Child Abuse Investigation Team from Hillingdon and Ealing Boroughs.
