A bomb squad was called in to investigate a suspicious package found inside the Wells Fargo headquarters in downtown San Francisco Monday morning.

San Francisco police received a report of a suspicious package inside of a building in the 400 block of Montgomery Street shortly before 8 a.m., Officer Gordon Shyy said.

Wells Fargo spokeswoman Holly Rockwood confirmed that the object was found inside the company's headquarters at 420 Montgomery St.

Wells Fargo was scheduled to be open that morning despite the holiday, but ended up being closed for several hours because of the bomb scare, Rockwood said. 

Streets in the area were closed to traffic during the investigation, but were reopened at about 1 p.m.
