A missing 14-year-old boy who disappeared from his family's home in Georgetown late Sunday night has been located safe and sound about 15 kilometres away, police say.

A CN worker spotted Adam Thompson near Heritage Road and Bovaird Drive in Brampton at around 4 p.m. Monday afternoon.

Thompson, who has autism, had left his home at around 10:30 p.m. Sunday after getting into an argument with his parents over computer use.

At the time of his disappearance he was not wearing any shoes.

"Obviously we need to have a chat with him," Insp. Jackie Gordon of Halton Regional Police told CP24. "A lot of resources went out to try and find this young man who had clearly been very upset with his situation at home and we want to make sure that doesn't happen a second time."

A command post had been set up to co-ordinate the search, which drew in volunteers from Thompson's family and the community at large.

Gordon said it's too early to tell how the boy covered such a significant distance, but said his emotional state may have played a part.

"Sometimes when people are in that state they don't feel pain," she said. "They are upset, they are concerned, they are anxious and they don't feel any pain in many instances."

Gordon added that Thompson's parents were "elated" to hear that he had been found.
