School gates knife: Staff 'secured' weaponpublished at 14:36 Greenwich Mean Time 6 December 2018
School staff tackled a young boy brandishing a large knife outside school gates, it has emerged.
The footage of the child outside Downend School near Bristol was shared by parents with the BBC.
The school did not respond to a request for comment but a letter to parents from headteacher Lisa Howell has been seen by the BBC.
The letter says: "A knife was secured by duty staff, the police were called and the knife and the details of the incident have been passed to investigating officers who assure us that appropriate and robust action is being taken."
The headteacher said the boy carrying the knife "has no connection with the school and we expect no further issues".
The school is now bringing forward lessons on knife crime and has asked police to run an "extended clinic" on the issue.
