The new principal of Walworth Academy has written to the families of all students warning that the school may carry out random searches of pupils to detect knives and other weapons.
Two Walworth pupils – Dogan Ismail and Junior Nkwelle – were stabbed to death in separate incidents during 2012. The academy also recently opened a David Idowu Peace Garden devoted to the memory of another pupil who died as a result of knife crime.
Yvonne Powell, who took over as principal at the start of the year, wrote: "There may be occasions when we will do random searches. Any search will always be carried out sensitively and we will use wands which will detect any metallic object."
Ms Powell stressed that the school has a "zero-tolerance approach to violence and weapons" and that any student found with a knife or other weapon will be expelled from the academy and reported to police.
