A school in Danbury went into lock down yesterday after Danbury Police received a call about an agitated man with a firearm near Great Plain Road. St. Gregory School was notified as a precaution and placed on lockdown. When officers arrived on scene, they quickly established the homeowner was legally carrying a firearm on his property after spotting a bear in his yard. Others in the area notified police that a bear was seen wandering through the neighborhood. The lockdown was lifted and dismissal procedures were not impacted. It’s a busy time of year for bears and the state Department of Energy and Environmental Protection urges people not to approach bears. Residents should remove birdfeeders from the yard and store garbage in a secure container.
