After reading about the theft in the newspaper, the Good Samaritan contacted police to arrange a $500 donation to replace the bike.
The teenager was attacked by two young men during a morning outing on Aug. 13. After one asked for a ride and was turned down, he punched the boy as the other suspect grabbed the bike. Both escaped a police search.
The first suspect, described as a white man about 17 to 18 years old, had short blond hair, freckles and light eyes. About 5 feet, 7 inches tall and weighing about 150 pounds, he wore jeans and a gray T-shirt, according to the police report. He rode the bike as the pair fled south on Alma Street.
The second suspect, a black man about 18 to 19 years old, wore jeans and a white T-shirt. He stood nearly 6 feet tall and weighed about 180 pounds with short, curly dark hair and medium complexion.
Police spokesperson Nicole Acker said there was no update on the investigation. Anyone with information about the robbery can call police at 330-6300.
