Documentary filmmaker Franny Armstrong was confronted by a group of young teenage girls as she was walking in North London Monday night, media reported. "I was texting on my phone so didn't notice the girls until they pushed me against the car," the Guardian newspaper quoted Armstrong as saying. "I saw that one of them had an iron bar in her hand. It was more than a meter long."
