An 8-year-old boy suffered multiple broken bones when an 18-year-old allegedly picked him up and threw him over the safety railing of a water slide in Minnesota, causing the boy to plunge about 30 feet, authorities say.
The teenager, 18-year-old Roman Alexander Adams, of Maple Grove, Minnesota, was arrested and charged with third-degree assault in the incident last Tuesday, PEOPLE confirms.
Adams was behind the boy in line at the water park but the individuals did not know each other, police say.
Questioned at the scene by police, Adams, who was in the park accompanied by a female professional personal care attendant, exhibited “some developmental disabilities,” Apple Valley Police Capt. Nick Francis tells PEOPLE.
“The male gave a statement that the line was moving too slow, and so he picked up and pushed the 8-year-old over the top of the slide platform,” he says.
“He understood that doing that was going to cause harm to the individual, he knew that by throwing him over he knew the individual was going to be hurt, he shouldn’t have done it, and he admitted to picking this kid up and pushing him over,” Francis says.
