South Glens Falls investigators worked with New York state troopers to identify Ross as the man the girls saw following them, Judd said. The families of two of the girls filed official complaints.
Ross was arrested Tuesday during a traffic stop, The Post Star reported. He was in his own vehicle when the stop took place.
The complaints against Ross in South Glens Falls were not the first, The Post Star reported. A similar complaint of him taking pictures of children from his truck was lodged in June in Lake George.
The newspaper reported that Warren County sheriff’s deputies watched Ross and confronted him, but no charges could be filed because taking photos in public is not a crime.
He did not follow the children in the Lake George incident.
"It appears he escalated his behavior," Warren County sheriff's Lt. Steve Stockdale told The Post Star.
Police officials said that investigators notified the owner of Mr. Ding-a-Ling about the allegations against Ross, but he was allowed to continue driving his truck between the June and October incidents. The Post Star reported that calls to the company seeking comment had not been returned.
Mr. Ding-a-Ling was established in 1975 and has grown from one truck to 66 trucks, the company's website says. The trucks operate from New York to Maine and Vermont.
The operator of Mr. Ding-a-Ling of the Adirondacks wrote in a post Thursday on Facebook that Ross was in no way affiliated with his truck.
“Just wanted to let everyone know that has nothing to do with our truck here,” the post read. “I’m so mad about the driver there tarnishing our brand.”
He wrote that “bad apples” pop up in businesses everywhere, but that he wanted to reassure his customers.
“Most of my customers are like family and friends,” the post read.
