COLUMBUS, Ga. - Authorities say two men accused of taping razor blades to playground equipment at a Columbus park last year have been sentenced to prison.

The Columbus Ledger-Enquirer reports that 18-year-old Gary Bryan and 24-year-old Derrick Fullum both pleaded guilty to reckless conduct, and were both sentenced to a year in prison on that charge. Authorities say the two also pleaded to guilty to first-degree arson stemming from an April 2010 fire, and both men will serve six years for that crime.

Muscogee County Superior Court Chief Judge John Allen issued the sentences Monday after both men pleaded guilty to reckless conduct and arson.

Authorities say the men admitted to taping razor blades to playground equipment in May 2010. A 2-year-old found one of the blades and told his mother, who informed police.
