PHOENIX (3TV/CBS 5) -

A Phoenix Wells Fargo location near the I-17 was evacuated Monday due to a suspicious substance found, according to the Phoenix Fire Department. 

Phoenix Fire units were called to the business in the 11600 block of north Black Canyon Hwy and west Cactus Road.

Authorities say their initial reports indicate a brown substance was left on keyboards and chairs.

Hazmat crews and Phoenix police's bomb squad investigated the substance and determined it was sand.

Phoenix police said a former employee is suspected of spreading the sand in the office.

No arrests have been made.
