Bluffdale Elementary School, 14323 S. 2700 West, was placed on lockdown about 1 p.m. after someone spotted what appeared to be a man with a shotgun across the street.

Salt Lake County Sheriff's Lt. Paul Jaroscak said deputies swarmed the area, but eventually called off the search without finding anyone.

The lockdown, in which no one was allowed in or out of the school, was lifted after about 45 minutes.
