MP: 'A lot of trolls move into physical stalking'

A lot of internet trolls who harass people in the public eye online "move into physical stalking," according to Conservative MP Nadine Dorries.

Ms Dorries, who was plagued by severe trolling and physical stalking herself, told Good Morning Britain authorities needed to be better trained and more aware of safety legislation brought in to protect victims of online abuse if the problem was to be tackled.
