A Starbucks in north Scottsdale has reopened after a mysterious white powder found in a roll of coins Thursday turned out to be harmless, according to Scottsdale police.
The business at 32421 N. Scottsdale Road, near Lone Mountain Road, was evacuated about 8 a.m. after a cashier discovered the powder.
The incident came a day after two bank branches in the East Valley, and four in Phoenix, received letters containing a mysterious white powder.
Chase banks and other financial institutions have been sent more than 30 threatening letters as part of a nationwide scare this week, according to media reports.
Hazardous-materials crews from the Scottsdale Fire Department were called to the Starbucks, but they turned over the powder to authorities, according to Tiffani Nichols, fire department spokeswoman.
Three Starbucks employees were exposed to the powder, but no injuries were reported, Nichols said.
The FBI field office in Phoenix, which is involved in a joint investigation with the U.S. Postal Service in the bank letter incidents, is not involved in the Scottsdale incident at this time, but would assist if called upon, according to FBI spokesman Manuel Johnson.
Johnson said Thursday that the Starbucks incident does not appear to be connected to the white powder incidents at the banks.
