Residents of a Robbinsdale home for seniors have been allowed to return to the facility following an evacuation over the weekend.
It happened Saturday afternoon at Copperfield Hill, an assisted living facility located on 40th Avenue.
Around two dozen people were evacuated from a building in the facility called "Lodge" due to the apparent spraying of an animal repellent, and "several were sickened," the Star Tribune reported.
The paper says this came after authorities received a call that residents on the second floor were falling ill.
Some reported having trouble breathing, and ultimately five people were taken to the hospital to be treated, WCCO reports. They have all been discharged.
It's unknown what kind of animal repellent was involved or why it was sprayed, but KARE 11 says authorities found the repellent "in a trash can" and do not know who sprayed it.
Whether or not this is a possible criminal matter is still not clear.
