The break-in was reported shortly after 11 p.m. Thursday at a multi-million-dollar house on San Vicente Boulevard, prompting a massive response from Los Angeles police.
More than a dozen officers arrived at the scene with guns drawn, and news video showed an LAPD helicopter circling overhead.
According to a police spokesperson, the robbers entered the home through a rear glass door. Armed with a crowbar, they wore masks and all-black clothing.
The suspects made off with a safe and miscellaneous property, the LAPD said.
No injuries were reported.
