BOULDER, Colo. -- Letters containing white powder were opened at the Boulder Jewish Community Center and the Congregation Har HaShem, forcing evacuations and quarantines at both locations Monday morning, the Boulder County Sheriff's Office said.
The powder was field tested at both locations and deemed not to be toxic or a danger to humans, the sheriff's office said.
The letter sent to the Boulder JCC contained a message that read "your (sic) have enemies" and included a white powder that was opened about 8:30 a.m.
Sheriff's deputies responded to the center, evacuating the building at 3800 Kalmia Ave. The office, the people who were in contact with the envelope and the envelope were quarantined.
The Boulder County Health Department, the Boulder County Hazmat team and the Boulder County bomb squad investigated and field tested the powder, determining it was benign and not a threat to humans.
The powder will be sent to a state lab for final confirmation. The investigation into the source of the letter will continue, the sheriff's office said.
Moments after the announcement the powder at the Boulder JCC was benign, hazardous materials crews responded to Congregation Har HaShem (3950 W. Baseline Road) on a similar report of a suspicious envelope.
After tests were performed, it was determined the powder was not toxic.
"When events like these arise, the Board and Staff of the Boulder JCC take them very seriously," Boulder JCC said in a statement. "We place the safety and well-being of our community as our highest priority. We will continue to maintain a high level of safety and security."
Programs at both places resume normally on Tuesday.
