(1st REPORT, 2:14 p.m.) On Thursday, January 27th, the Great Falls Police Department was made aware of a potential threat to CMR High School.

The GFPD said in a news release that the threat was specific to CMR and said the action would take place the morning of Friday, January 28th. The threat referenced firearms and explosives.

On Thursday afternoon, CMR will release school at the normal time under ‘Release with Care’ conditions. ‘Release with Care’ requires school staff to be out and vigilant.

The GFPD plans to release an update at about 4 p.m. on Thursday to announce whether school will be in session on Friday.
