SAN FRANCISCO (CBS SF) — Three suspects remained at large Tuesday after they allegedly broke into a 79-year-old woman’s San Francisco Bayview District home, pinned her down and robbed and ransacked the residence, authorities said.

The incident took place in a home in the 1500 block of Van Dyke Ave. early Monday afternoon. San Francisco police said they responded to a call around 1:33 p.m.

The woman did not report being injured in the robbery, and the three suspects, described as men in their 20s, remain at large. Police did not immediately release detailed descriptions of them.
