Police arrested six kids in north suburban Gurnee for allegedly using homemade bombs to blow up part of a man's trampoline.
When the man looked outside, he saw several boys on skateboards and something on the trampoline.
Responding police found three homemade bombs, two of which exploded.
The boys, ages 12 and 13, were found nearby.
All six were arrested and charged with disorderly conduct and criminal damage to property before being released to their parents later that evening.
Police say information to build the kind of bombs they found is readily available on the internet.
