The San Francisco Police Department is investigating a brazen midday home invasion robbery, after a man was surprised by a gang of thieves in his bedroom.

According to the SFPD, the crime occurred at 1 p.m. Tuesday, on the 800 block of Ellsworth Street, which runs near Alemany Boulevard.

Police say that the victim, a 42-year-old man, was in bed when two men who looked to be 25 years old walked into his room. (Before anyone leaps on the issue of a man in bed at 1 p.m., please note that we don't know his work schedule or current state of health.)

One of the invaders "had a handgun," police say, which he kept out as his colleague and two additional suspects "ransacked [the] entire house," police say.

The four men stole a rifle, cell phone, laptop, and necklace from the house before hopping into a car and fleeing the scene.

As of publication time, the four men remain at large. According to the SFPD, no arrests have been made in the case.
