AUBURN, Calif. -- The FBI was called out to investigate a suspicious bag in Auburn Wednesday, just one day after a pipe bomb was found near the city's Department of Motor Vehicles office.

Authorities were called to a building under construction at Maidu Drive and Auburn-Folsom Road around 9 a.m. after there were reports of a suspicious device, possibly a bomb, at the site.

After a short investigation, the FBI said it turned out to be empty beer cans in a paper bag. But tensions are still high from the pipe bomb found.

On Monday, a similar device was found on the front steps of an Auburn courthouse.
