Luton Town Hall was evacuated this afternoon after a security threat was made in a phone call.
Police cordoned off the building and a large area of the town centre after the alert at 3.41pm.
Wellington Street, Dunstable Place, Gordon Street, Upper George Street and the area in front of the Town Hall were all closed off.
Officers with sniffer dogs swept the building, which has now re-opened.
The Police and Crime Commissioner election polling station was moved to Luton Library Theatre for a short while but has now returned to the Town Hall.
Luton Borough Council chief executive Trevor Holden said: “We had a call to the Town Hall purporting to be a bomb threat.
“I was very impressed with our staff – they worked seamlessly with the police.
“If this was a crude attempt to disrupt the election it has fallen flat on its face.”
