(CNN)A live pipe bomb was found at an Iowa community center serving as a polling place for a special election, Ankeny police confirmed in a statement.
Police said they responded to a call about a suspicious device at 9:25 a.m. Tuesday outside the Lakeside Center, which was being used as a polling place for the Ankeny Community School District special election.
According to the statement, the building was evacuated and a perimeter was established. The device was determined to be live and it was "rendered safe" by a technician from the state fire marshal's office at about 11:50 a.m.
Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives and FBI offices were at the scene as well, according to the statement.
Police say that there have been no other pipe bombs or devices found or reported in the city. An investigation is ongoing, according to Ankeny police.
Polk County Auditor and Commissioner of Elections Jamie Fitzgerald said on Twitter that people walking their dog noticed the device. He said it was not clear how long the device had been at the site and that it may not have been election-related.
"At this time, there is no evidence that the polling place was the target of the pipe bomb," Iowa Secretary of State Paul Pate said in a statement. "There is no indication of an ongoing threat to Iowa polling places."
