The San Jose bomb squad raced to Willow Glen Friday morning after receiving a report of a suspicious package with a threatening note at a nail salon on Lincoln Avenue.
But at about 11:30 a.m., the danger appeared to be over, though police hadn't said exactly what the issue had been. Authorities said they wanted a forensic expert to determine what the powder was. But by noon, they had declared the situation over, despite keeping some streets closed until 1:15 p.m.
Bomb crews had sent in a robot to extract a package, first called in at 8:50 a.m. in the 1300 block of Lincoln Avenue, Officer Jose Garcia said.
Police did not disclose what the note said. But an image seen on the Bay Area News Group web site, looked like the note was handwritten in blue marker and was in Vietnamese. The note was lashing out at the owner and employees, and threatened to use a hand grenade against them.
Willow Glen Elementary School students were asked temporarily to stay inside, according to school district spokeswoman Karen Fuqua.
