Police say the robbers made off with an undisclosed amount of cash Saturday from the Pacific Marine Credit Union in Mira Mesa.
No customers were in the bank at the time.
“During the robbery one the robbers dragged a teller by the teller’s hair into the bank’s vault and ordered the teller to give him money while pointing a gun at her head,” Foxworth said.
No shots were fired and no one was injured, but officers say the robbers dropped more than a dozen rounds of ammunition on the bank floor.
Police say the suspects escaped in a maroon pickup with an extended cab, a white decal on one side and a toolbox in the bed.
The tellers told police all three robbers wore masks and dark pants and shoes. One was described as 6 feet-2 inches tall, 230 pounds, wearing a mechanic's-style jumpsuit under a sweatshirt. He had pulled some mesh material, possibly pantyhose, over his head and knotted them at top. He wore a bandanna across his face.
A second robber, about 5 feet-6 inches tall and 160 pounds, wore a gray hooded jacket.
The third robber was 5 feet-3 inches tall, 130 pounds, and wore a gray or black hooded jacket.
