WENN reports Hilary Duff’s mother Susan went on a car chase with her two daughters after she spotted a man believed to be stalking Hilary outside their home in Toluca Lake. Why? “Enough is enough,” she said. “There has been repeated incidents, and I wanted them to stop.” After a 50 minute chase, the man finally stopped at his own home and called the police. “He said he had been at our house because of his 16-year-old daughter. But his daughter wasn’t with him,” Susan said. But Los Angeles police say the man was investigated and cleared of any wrongdoing.
