EYOTA -- A 21-year-old Rochester man suffered serious injuries Thursday after he was ejected from an ATV as an Olmsted County Sheriff’s deputy attempted to pull him over.

A deputy on patrol in the 7800 block of 10th Street Southeast about 5:20 p.m. spotted an ATV being driven on the road, according to Capt. Scott Behrns. The deputy could not see the ATV’s registration and pulled closer to the ATV to see it. As the deputy got closer, the driver of the ATV did a U-turn in the middle of the road and “took off” at about 50 mph, Behrns said.

The deputy activated his lights and sirens, but the driver of the ATV did not stop. The deputy noted that he didn’t believe the driver was attempting to flee but rather did not hear the squad’s sirens, Behrns said.

At one point, the driver looked back and spotted the deputy. It was at that point the man, identified as 21-year-old James Hart Jr., veered right and lost control of the ATV. Hart was ejected from it and landed on his head on the roadway, Behrns said. Hart was not wearing a helmet.

He was taken by ambulance to Mayo Clinic Hospital-Saint Marys where he underwent surgery for his injuries, Behrns said.
