Four teenagers have been arrested in Cobb County on charges of robbing cyclists on the Silver Comet Trail near Austell, police said.

Three juveniles and 17-year-old Isaac Lee Kemp of Douglasville were charged with aggravated assault and robbery by force, said Sgt. Dana Pierce, a Cobb police spokesman.

The robberies occurred in mid-June on the popular biking and jogging trail near where it passes under Austell Road. Both victims were men —- one 49, the other 62 —- and were not seriously injured, police said.

Pierce said the four youths would block the path, then knock the rider off the bike and go through his pockets.

The juveniles —- two 14 and one 15 —-lived near the trail. They were released to relatives after being charged. Kemp is held on $25,000 bond at the Cobb jail, Pierce said.
