The 28-year-old woman was in the parking lot of a convenience store near 80th Avenue and King George Highway just after 3:30 a.m. PT Sunday when the confrontation began, police said.
Surrey RCMP Sgt. Murray Hedderson said the dark-coloured SUV the followed her as she walked into a mobile home park in the 8200 block of King George Highway.
"The verbal exchange continued at the trailer park, and at one point one of the occupants of the dark-coloured SUV fired a single gunshot, which struck the female in the lower leg," he said in a written statement.
The SUV then sped away.
Hedderson said police have not determined a motive for the shooting but at this point don't think the incident was random.
