A Sudbury man broke through thin ice on Long Lake on Sunday when he was riding his dirt bike, said Greater Sudbury Police Service.
Police and firefighters were called for a water rescue around 1 p.m., but the man was able to make it safely back to shore.
His dirt bike sank.
Police Chief Frank Elsner said on Twitter the incident put emergency personnel at risk.
"Poor choices like today's put emergency personnel lives at risk. At least he has something to talk about at his next Mensa meeting."
Police remind everyone that the area ice is very thin.
“It is too thin for any vehicles to be out on the ice,” Greater Sudbury Police said in a news release. “Extreme caution should always be exercised when crossing lakes, rivers or any iced surfaces.”
