HARRIS COUNTY, Texas -- The Harris County Sheriff's office brought in bomb-sniffing dogs Wednesday evening to comb through the buildings of the Lone Star College in Cypress after two notes were left around the campus.

The notes were left in the women's restrooms at the library and student center.

Both notes mentioned a bomb on Oct. 10 and both end with smiley faces.

Lone Star officials don't think there is any danger, but they are adding patrols on Thursday just in case.
