Police in the San Fernando Valley were searching Thursday for an armed serial robber dubbed the "Bandana Bandit."
The man has been linked to nearly 10 robberies in the past two months, most of them in the North Hollywood area.
Victor Frausto and his girlfriend were walking in the parking garage of their gated complex near Laurel Canyon Boulevard and Chamberlain Street in San Fernando when they were attacked.
It happened around 3 a.m. on July 19 just as the couple was about to step into the elevator.
Everything happened very fast, Frausto said.
"He had a pistol in his hand," Frausto said. "He had a bandana and his head covered with a beanie."
The gunman ordered the couple to get on the ground and empty their pockets.
When the man threatened his girlfriend, Frausto said he went on the offensive.
"We got into a little scuffle," Frausto said. "He pistol whipped me in the head. I suffered a fractured nose."
The robber escaped.
The man targeted people walking to and from their cars, often in parking garages, late at night or in the early morning hours, police said.
Frausto and his girlfriend decided to move out of their building after the incident, saying they no longer felt safe.
The robber was described as a man around 20 years old, about 5 foot 10 inches tall and weighing about 165 pounds.
