PHOENIX (AP) -- The Arizona Department of Public Safety's headquarters in Phoenix was deemed safe after being evacuated because of a bomb threat Sunday night.

DPS spokesman Bob Bailey says the Phoenix police dispatch center received the threatening call around 9 p.m. Sunday. Police say that call came from a cell phone.

Bailey said the complex was evacuated, and the agency's 911 calls were diverted to Phoenix police. Tucson and Flagstaff dispatch centers took over DPS dispatch responsibilities for the Phoenix metro area until 10:30 p.m.

Bailey says DPS' explosive and ordinance disposal team conducted a sweep of the complex, and "all was found safe and secure."

The complex encompassed 20th to 23nd avenues on Encanto Boulevard.

Employees were allowed back into the building at about 10:30 p.m.

Investigators said they believe they might know who made the threat.
