Los Angeles police will be present daily on every public elementary and middle school come January, and on any private or charter campus that requests a visit, Chief Charlie Beck said Monday.

Some officers will be in uniform, some will be in plainclothes and the campus visits will be part of their routine patrols, Beck said.

He wouldn't say how long the patrols will last and whether the daily campus visits would be permanent.

The increased police presence around campuses - plus an announcement that L.A. will hold its annual gun buyback after Christmas instead of in the spring - was the city's response to Friday's massacre at a Newtown, Conn. elementary school.

During a 1 p.m. news conference at the police headquarters, Beck also gave a few more details about a 24-year-old man who was arrested Sunday on suspicion of making criminal threats. Beck said patrol officers found out that Kyle Bangayan of Pomona had allegedly posted comments on Facebook regarding committing violence at an elementary school.
