A television documentary about knife crime affected 17-year-old Gill Sands so much that she has launched a Facebook campaign.
Gill, who attends Archbishop’s School in Canterbury, was in tears after watching Stabbed - The Truth About Knife Crime on BBC 1.
The film showed graphic CCTV images of people being stabbed, interviews with grieving parents and victims as well criminologists thoughts on gang culture.
Gill, who lives in Wincheap and wants to be a teacher, says the documentary left her upset over the waste of young lives and grief of families.
She said: "The film really affected me. It was just disgusting to see people being stabbed for no reason and the casual way offenders treated taking someone’s life or maiming them.
“I just wanted to try and do something to help and thought a Facebook campaign would generate an anti-knife crime swell of opinion among young people.”
Gill has called the group profile Knife Crime Must Stop - Before It’s Too Late.
Already it has attracted more than 400 members.
She has also been in touch with the charity set up after the stabbing last June of Ben Kinsella, the brother of EastEnders actress, Brook Kinsella.
