Two men carrying guns held up the adult video and book store on West El Camino Real shortly before 11:20 p.m. on July 2, police said.
The men came into the store wielding semi-automatic handguns and demanded that the cashier fork over the money in the register, said Jaime Garrett, spokeswoman for the Mountain View Police Department.
The cashier complied, and the men fled out of the back door of VCO Adult Videos, located at 1063 W. El Camino Real, Garrett said. The men had their faces obscured by some kind of mask. They wore black sweatshirts, dark pants and dark shoes.
The robbers also took a cell phone. The amount of money stolen was not disclosed.
Detectives are reviewing store security footage, Garrett said.
The same store was robbed in December by a man who claimed to have a gun in his pocket.
Pool hall scuffle
A patron of California Billiards, a Mountain View pool hall, was arrested on July 4 after hitting an employee as she attempted to escort the man outside.
The incident began at about 11 p.m. when the man began arguing with another patron for "no apparent reason," according to Jaime Garrett, spokeswoman for the Mountain View Police Department.
The employee stepped in and attempted to guide the man outside. The man struck her once on the side of her head with an open hand, Garrett said. After hitting the woman, he fled, leaving behind a wallet and a key for a room at a Sunnyvale hotel.
At the hotel police found Kim Brandy, a 48-year-old Sunnyvale man.
Brandy was identified by the victim, arrested and charged with battery and public intoxication.
