Caroline Stuttle's mother is campaigning to warn other teenagers to take precautions while travelling abroad on their gap years.

Marjorie Marks-Stuttle has set up Caroline's Rainbow Foundation, in memory of her daughter, to help advise young people about the dangers they could face.

While the jury in Australia was considering its verdict this week, Mrs Marks-Stuttle was at a conference in London to help train students to read the warning signs that can alert them to trouble.

She used the conference - held in association with the Foreign Office, the Royal Geographical Society, and a team of former SAS officers and safety experts - to launch a video, which will be distributed to every sixth-former in Britain.

"The important thing is that the youngsters follow their dreams, but do their research and be safe," she said. "There are things like learning to walk away from a fight rather than sticking up for their rights.

"It's easy for youngsters to feel over-confident."
