LEBANON — A South Berwick ATV operator allegedly told Maine State Police troopers on Saturday that he didn’t know anything about an ATV crash involving a pedestrian in a campground located in an ATV mud racing and off-road park and that he didn’t own an ATV.

Recent injuries and dirt marks that were indicative of sliding across the ground led police to a different conclusion, and Franklin Mann, 47, of South Berwick was taken into custody.

The pedestrian sustained serious injuries, according to police, and was taken to Maine Medical Center in Portland. The victim’s name was not released, and no update on his or her condition was available.

The incident took place at 4 X 4 Proving Grounds, a 123-acre off-road park in Lebanon at about 11 p.m. Saturday. Maine State Police from Troop A in Alfred responded to a report that an ATV had crashed into a pedestrian and fled the scene.

“Troopers gathered information from multiple witnesses and a detailed description of the suspect was compiled,“ police said in a social media statement posted on Tuesday.

They located a man who matched the description of the suspect walking down a dirt path in the campground. Police said they confirmed Mann was the registered owner of the ATV and said witnesses on scene told them that Mann was the operator.

Mann was arrested and charged with Class B felony aggravated assault and Class C operating under the influence resulting in injury. Class C charges of leaving the scene of an accident with injury and misdemeanor Class D reckless conduct are pending, police said.

Mann was initially held at York County Jail on $25,000 bail. He made a first court appearance Tuesday ,where his bail was reduced to $2,000 and a corrections officer late Tuesday afternoon said Mann was in the process of posting bail.
