Knife arches could be put into Richmond’s schools in the “near future” following the daytime stabbing of a 15-year-old boy in East Sheen.

A Shene School pupil was knifed in the chest after school on May 7 at about 3.36pm after what is believed to have been an argument on a bus earlier that week with another teenager – who does not attend the Park Avenue school.

The stabbing, outside the Willoughbys Estate in Upper Richmond Road, led to renewed calls for a dedicated bus service for Shene and prompted secondary school headteachers to sit down and discuss the possibility of knife arches in schools.

It is understood they agreed to let Richmond Council’s director of children’s services, Nick Whitfield, work with police to decide if they should be introduced.

Richmond’s crime manager, Detective Chief Inspector Mick Allen, said: “I am convinced at some stage in the near future we will be deploying knife arches where appropriate.”

MP for Richmond Park, Susan Kramer, said the attack was evidence Richmond was not “immune from a spill over of violence from neighbouring communities”.

She added: “While it is alleged the incident was outside the school and the attackers were not pupils at Shene, parents need to have confidence pupils are safe. I am pushing the police for a knife arch that detects weapons to be used at the school as soon as possible.”

A spokesman for Richmond Council said it was “completely premature” to comment on the knife arch proposals.

Headteacher at Shene School, Lesley Kirby, said the community was shocked by what happened, but praised the way her staff and those at East Sheen Primary School – near to where the stabbing happened – rallied to help the youngster, who was rushed to hospital and is thought to be recovering well.

Speaking the day after the stabbing, she said: “They all pulled together fantastically today [May 8] and loads were out to support at the bus stop both yesterday and today.”

Transport for London (TfL) has continued to refuse the school a bus service for its pupils and, following the attack, Conservative parliamentary candidate for Richmond Park, Zac Goldsmith, Ms Kramer, council leader Serge Lourie and GLA members Caroline Pidgeon and Tony Arbour have all signed a letter to Boris Johnson asking him to rethink. Ms Kirby added: “We have been asking TfL for a bus and saying there could be issues with students coming from other areas. They did not listen.”

A TfL spokesman said it was in contact with the school and was helping “give support in addressing any behaviour issues”.

She said: “TfL continues to monitor bus capacity on the routes serving Shene School.”

A section of the Upper Richmond Road was closed after the attack and traffic was diverted along Sheen Lane until a van hit a barrier on the level crossing – forcing the lane to close from about 5pm to 10pm while Network Rail replaced it.

A 15-year-old youth from Hammersmith appeared at Richmond Magistrates’ Court on Monday charged with wounding with intent in connection with the stabbing.

No plea was entered and he was remanded in custody to reappear next Tuesday.

Three other teens, one 16-year-old and two 14 year olds, were also arrested in connection with the attack, but all three were bailed pending further enquiries.
