A 19-year-old Beach Park, Ill., man was arrested early Thursday after he set off a bottle bomb outside an Augustana College residence hall, police said.
Rock Island Assistant Police Chief Jason Foy said officers were called to the scene about 3 a.m. regarding somebody detonating the device.
Officers were directed to Westerlin Hall, in the 3200 block of 10th Avenue, where they found evidence of the device.
Brett M. Johnson was arrested in connection with the incident. He is charged with one count of disorderly conduct. He was taken to the Rock Island County Jail. His bond was set at $1,500, and he was released after posting bond.
Foy said no one was injured in the incident.
Such devices are made from 1-liter or 2-liter plastic cola bottles that are designed to make a loud pop.
According to the federal Centers for Disease Control and Prevention, the bombs are usually made with household chemicals. When the ingredients are combined and shaken in a capped container, the internal gas pressure causes the plastic bottles to expand and explode. Some of the chemicals chosen to make the device may be harmful.
