Police have charged two people accused of throwing a homemade bomb made of baking soda and vinegar into a neighbor's yard in Pittsburgh's Perry North.

Investigators said Zachary Walls and William Grimm are both charged with aggravated assault, recklessly endangering another person, arson and possession of explosive or incendiary materials.

Channel 11's Renee Kaminksi reported that the men targeted an 8-year-old boy. The boy's mother said the attack was part of an ongoing battle with neighbors.

The suspects told police they had problems with the family, so when they saw the homemade bombs on YouTube, they thought it would be funny to throw one in the family’s front yard.

“It exploded. She (the boy’s mother) came out of the door.  He said, ‘I’m sorry.’  It was baking soda and vinegar.  She hit the ceiling,” said Renee Walls, mother of one of the suspects.
