LOS ANGELES, Calif., – Four schools in the South Los Angeles area were locked down as a precaution today because of two apparently unrelated incidents.

About 7:30 a.m., an armed robbery near 41st Street and Avalon Boulevard left a person hospitalized with a leg wound, said Los Angeles police Officer Bruce Borihanh of the Media Relations office.

Police searched the neighborhood for the suspect, described as a man about 20-30 years old, Borihanh said. Wadsworth Elementary and Harmony Elementary were locked down as a precaution, according to the Los Angeles Unified School District.

The lockdown was lifted at Wadsworth about 10:30 a.m., but continued at Harmony until 1:15 p.m., the LAUSD reported. The perimeter search for the suspect was suspended early this afternoon, but police continued their efforts to find him, Borihanh said.

About 8 a.m., an unauthorized person was seen on the grounds of Miller Elementary, at 77th Street and Vermont Avenue, and that school was locked down, as was the Wanda Mikes Primary Center, which is on the same campus, according to the LAUSD.

A room-by-room search was conducted, and officials determined that the unauthorized person was not on the campus, the LAUSD reported. The lockdown of both schools was lifted about 11 a.m., according to the school district.
