DENVER, Colo. (AP) - Someone has spray-painted swastikas on at least one window of President Barack Obama's campaign office in Conifer, southwest of Denver

KUSA-TV in Denver reports (http://on9news.tv/R8paZL ) the building's owner says the vandalism happened overnight.

Jefferson County Sheriff's spokesman Mark Techmeyer tells The Denver Post that a deputy who went to the office Friday found other windows and five campaign signs also were damaged, but he didn't know the details.

Last week, a shot was fired through the window of an Obama campaign office in Denver.

The campaign hasn't comment on the latest incident.
