'Potter' actress steps up security

Harry Potter star Emma Watson has been forced to step up security after being stalked by an obsessed fan.

The actress was shocked to be confronted by an admirer who turned up at her school after learning that open lectures were being held. Watson is currently studying her first year of A-Levels.

A source told The Sun: "The man was an admirer who was over-zealous. He found out there were some open lectures at the school and attended them. He left Emma alarmed when he approached her and started talking to her about the Potter films.

"The school was informed and so were Emma’s parents. The decision was made to call in the police as the man was not known to her. A minder was also hired to be with her. The police spoke to the man and he was warned off in no uncertain terms. There have been further incidents since they spoke to him."
