SAN JOSE (CBS SF) – Several schools and libraries in the Alum Rock area of San Jose were on lockdown Thursday afternoon as authorities searched for a suspect in a home invasion robbery, a Santa Clara County sheriff’s captain said.

Around 11:20 a.m., deputies responded to a burglary in progress in the 14000 block of Chrisland Avenue in unincorporated San Jose, sheriff’s Capt. Rick Sung said.

Two women were inside the home at the time of the intrusion, and they told deputies that five men had entered the residence and that at least one had a gun, according to Sung.

Responding deputies saw the suspects trying to flee and were able to apprehend four of them, Sung said. The fifth evaded authorities, and they are still searching for him.

A sheriff’s helicopter was deployed for the search, as were K-9 units from the San Jose Police Department, Sung said.
