San Carlos Apache government, school buildings locked down for 'credible threat'

Posted at 1:11 PM, Feb 11, 2019

SAN CARLOS, AZ — A credible threat has led to the lockdown of all tribal and school buildings on the San Carlos Apache reservation.

A statement posted to the tribe's Facebook page says the lockdown was put in place at 9:30 a.m. Monday and would remain "until further notice."

"This order is in response to a credible threat by an individual known to have possession of firearms," Chairman Terry Rambler wrote. "The Tribe's law enforcement authorities are aware of this threat and are actively searching the area to apprehend this individual."

A post by the San Carlos Apache Police Department said officers were searching for Isaiah Polk and said he made "statements he would kill officers and people."

Polk was arrested without incident around 1:45 p.m., police said.

All San Carlos Unified School District buildings were also placed on lockdown, though the procedures were changed to lockout based on updated information from the police department, the district said. The change allowed classes and planned after-school activities to continue as normal while preventing people from coming onto the school grounds.

Officials have determined it is safe enough to allow parents or guardians to check their students out of school, and buses will run on the early Friday schedule. All staff will be allowed to leave once all buses and students have done so, the district said on Facebook.

Girl's basketball practice will be the only after-school activity, and will continue with security and law enforcement present.

Anyone with information on Polk's location is asked to call (928) 475-2311 and/or 911.
