Pawtucket police said Friday that a suspicious item left on a sidewalk was apparently an expansion tank for a home heating system.
Police, firefighters and a bomb squad secured the scene on Roosevelt Avenue just before noon.
Police Maj. Arthur Martins said authorities believe the item may have fallen from a passing vehicle or been abandoned as trash.
Neighbors were told to shelter in place. There was no evacuation order.
Police cleared the scene about an hour later.
