Police searched for five armed men in connection with a brutal home invasion robbery in San Francisco's Outer Richmond neighborhood early Thursday, authorities said.

San Francisco police said they received a report of the robbery in the 500 block of 40th Avenue at 2:55 a.m.

Between five and 10 residents -- most of them college students -- were at a single-family residence when five black men in their 20s entered the home. The suspects took electronic devices and an undisclosed amount of cash, according to police.

“Five guys came in with guns and immediately began knocking down doors,” a resident told KTVU. “They started hitting us and dragged us all out into the living room.”

Among the electronics stolen were multiple iPhones, an Xbox, and a laptop, police said.

Police said the suspects were reported to have in their possession two handguns and a knife. The knife was recovered from the home.

The students were shaken up, but no one suffered any major injuries.

All five suspects fled the scene on foot and have not been detained. Police have not released how the suspects entered the home or if the residence was targeted.
