A purse snatching turned into a high-speed chase from Buena Park into Compton. Three men grabbed a woman's purse, which contained $2,500, as she left a bank in a supermarket and walked to her car in the parking lot of SuperOne Grocery, 5301 Beach Blvd. just after noon. The men pushed her to the ground and snatched her Louis Vuitton purse, Buena Park police Sgt. William Kohanek said.
