A BRENTWOOD School pupil has been expelled for taking inappropriate photographs of members of staff using a mobile phone.
The revelations have "greatly upset" staff at the top fee-paying school, according to headmaster Ian Davies, who has strictly curtailed the use of mobile phones.
The boy had been initially suspended for taking a picture of a staff member two weeks ago.
But, following his readmittance to the school, further images of two other members of staff were found in circulation dating back to September 2011.
The pupil was expelled from the £14,000-a-year school, founded in 1588, last week.
The Gazette understands that one of the three victims called in police to investigate the matter on January 31. Inquiries are on-going and police are liaising with the school.
Parents have now been warned their children will be allowed to use mobile phones only during break and lunchtime and are banned from using them in the dining hall and library.
In a letter to parents, Mr Davies confirmed a student was suspended from the school for "using a mobile phone to take an inappropriate picture of a member of staff".
He added: "Having carefully considered the evidence, and having secured further information this week, the pupil concerned will now leave the school.
"As a result of this incident, I intend to review our mobile phones policy, which is on display in every classroom around the school.
"Up until now, we have tried to balance the educational desire to ensure that students use the technology sensibly (although this sometimes seems to elude even adults) and the need to protect both students and teachers from the unwelcome effects of the misuse of this technology.
"Clearly, the incident has greatly upset many of our teachers, and I would welcome your thoughts on our current policy."
The new policy demands that, during school hours, mobile phones can be used only during break and lunchtime and they should only ever be used for school-related matters and essential communication with home.
Mobile phones are banned from use in the dining hall or library and they must not be used at school to access the internet or e-mail, take photographs, create moving images or record sounds.
If they are used inappropriately, mobile phones will be confiscated and passed on to heads of year and an appropriate sanction will be issued.
