In 2002, 15-year-old Kara Chamberlain was kidnapped at gunpoint, held for 18 hours, drugged and assaulted.

After her escape, police discovered her kidnapper had been involved in the murder of at least three other people in Virginia, US.

Now a mum-of-two and a public speaker with a career in law enforcement behind her, Kara uses social media to educate others about what happened to her and how to understand trauma.

She spoke to BBC Newsbeat about her experience.
