A primary school has banned the chairman of the governors from its premises after he threatened to expose a series of violent incidents involving its pupils.
In one of the most serious episodes at Dorchester Primary School, a six-year-old boy stabbed a teacher with a pencil. In another, a boy was suspended after physically assaulting a girl.
But when chairman of the governors Chris John, 40, tried to raise concerns to the authorities about the children's behaviour he was barred from entering the school in Dorchester Road, Worcester Park, by Sutton Council.
Mr John, who has a daughter at the school, is only allowed in the grounds to pick up his child but has been warned if he enters the buildings the council "may have no option but to take further steps."
The governor of four years claims that there have been disturbing incidents involving five unruly children but feels the incidents are not being investigated sufficiently.
He also claimed that attempts were made to keep a disruptive pupil at home while the school was being officially inspected by Ofsted.
He said: "The school is very concerned about image, very much in line with the London borough of Sutton.
"Fur coat but nothing in the fridge is the way I would sum it up."
Mr John, had been approached by parents and teachers earlier in the year raising their concerns.
He said: "Staff didn't feel like there was any continuity in behaviour management, they felt some teachers were managing it well, but others were not.
"The governing body raised the issue with headteacher Louise Austin who resisted the need for any type of behaviour management policy."
Mr John said the pupil who had stabbed a teacher in the arm with a pencil on May 21 was a classic example of how the school's policies were failing.
He claimed this six-year-old was allowed to routinely wander the school as the staff had effectively given up on him attending classes.
A caretaker once found the youngster in the street outside school ground wearing his socks.
Mr John has met with MP Glenda Jackson who has written to the council to have the ban removed.
The National Governors' Association is also considering a complaint to the Secretary of State.
Mr John is seeking legal advice.
He said "I simply want these behaviour issues dealt with for the good of the children and the school."
A council spokesman said: "Issues have been raised at the school that affect Mr John.
"These issues are being investigated appropriately and until this has concluded, Mr John has been requested not to enter the school buildings."
