Anna says she was pushing her one-year-old’s stroller near the seawall by Cambie Bridge and the marina around 8:45 a.m. on July 28, when a man came up behind them. “He was screaming and yelling threats and obscenities, but he was yelling them to himself, as if he was having a fight with someone inside his own head,” Anna said. She says she decided to cross the street, but the man followed, and his obscenities became more pointed towards her. “Then he started to yell, you f –ing b—. You think I can’t catch you? I can f—ing catch you, you f –ing b—,” she said. Anna says she yelled for help and ran down a ramp onto the seawall where bystanders intervened and surrounded her and her child. “I feel shaken to my core because I had the baby with me.
