Stonington — Police warned residents Wednesday that aggressive minks have been spotted at Stonington Point and even chased a person Wednesday morning.

In a recorded message sent to residents, Capt. Todd Olson urged people to stay away from a mink if they see one because even though they resemble a pet ferret, they are not friendly. Minks are territorial animals.

He said the department's animal control officer notified the state Department of Energy and Environmental Protection about the minks and the agency is looking into the situation. 

In the past, the borough has been plagued by skunks and rats at times. A mink farm once operated in town.
