A knife-wielding female robber barged into an apartment in Long Beach’s Zaferia district over the weekend and threatened the man inside, according to police.

The robbery happened around 7:15 p.m. Saturday in the 1400 block of Obispo Avenue, Long Beach police spokeswoman Nancy Pratt said.

The man who lives at the apartment opened his front door after hearing a knock “and was met with a female armed with a knife,” Pratt said.

After threatening the man, the robber came inside and grabbed cash, jewelry and an electronic device before fleeing to a car that was waiting outside, according to police.

Detectives are still looking for the robber. It doesn’t appear she knew her victim, “But it’s very early in the investigative stage,” Pratt said.

Police asked anyone with information to contact Det. Fermin Gonzalez at 562-570-7464. Anonymous tips can be sent to Los Angeles Regional Crime Stoppers by calling 1-800-222-TIPS (8477) or visiting lacrimestoppers.org.
