Police in Chatham-Kent are warning people that certain locations of the ice are not safe for ice fishing.
Around 11 a.m. on Saturday, Ontario Provincial Police (OPP) Chatham-Kent officers, Chatham-Kent Emergency Medical Service (EMS) and the Joint Rescue Coordination Centre (JRCC) were called to assist a group of ice fishers who had become stranded on the ice on Lake St. Clair.
Police said three people had to be air lifted to safety while the others managed to return to shore on their own.
"Due to fluctuating temperatures the ice is unstable," said OPP in a statement. "Large cracks have formed creating gaps in the ice making a very dangerous situation."
Police are asking the public to use extreme caution on the ice. They add that you should always make sure you have the proper safety equipment and carry a communication device.
