Obama staff inside Westside office when vandals struck

Staff members were in President Obama's Westside campaign office when several large plate glass windows and a glass side door were smashed, sources said Friday.

Initially, officials thought BBs or pellets were used in the vandalism in the incident Thursday that took place at 7:25 p.m. in the 6700 block of South Centinela Avenue, but sources said no evidence of those items was found.

Authorities are also looking at whether the vandals used a crow bar, tire iron or other large instrument to smash the windows.

Though the campaign workers heard breaking glass, they did not see anything, sources said. A Los Angeles Police Department spokeswoman initially said no one was in the office at the time.
