Police arrested two more juveniles Monday afternoon for setting off “bottle bombs,” this time in the Cedarcroft subdivision in western Peachtree City.

Police also have filed charges against four juveniles for setting off “bottle bombs” on the cart path in the area of Georgian Park Wednesday night.

In both cases the juveniles left the scene on golf carts but were later identified and apprehended, police said.

In the Cedarcroft incident, two witnesses saw two juveniles thrown an object into a green PVC sewer pipe, police said. Seconds later a loud explosion was heard.

The two juveniles were charged with manufacturing an explosive device. They were identified because the golf cart registration number was spotted by witnesses, police said.

The juveniles in the Georgian Park incident were located by police, but they refused to stop the golf cart they were riding on, police said. Three of them jumped off the cart eventually, but the driver was stopped a short time later on Turtle Bay, police said.

All four juveniles from the Georgian Park incident were charged with manufacturing an explosive device and obstruction of a police officer.

Charges from all the cases will be brought forward in Fayette County Juvenile Court.

Police Chief Skip Clark said the police department is concerned about these incidents because of the potential for someone to be injured by one of the homemade explosives.

While the Georgian Park juveniles were being interviewed last Wednesday evening, another group of juveniles set off another device in the area of Cove Road and Fishers Luck, police said. Police learned those juveniles had purchased chemicals to make the bombs at a shopping center just before the incident.

The next morning police received more bottle bomb reports with devices found in the Timber Walk, Interlochen, and Carnellian Lane areas, police said. One of those bottle bombs was placed in a homeowner’s mail box, police said.

Police have offered a $500 reward for information leading to the arrest and conviction of persons responsible for these incidents.
