A jail inmate on work release has become a "hero of sorts" for nabbing a man suspected of trying to steal a historic cannon from the lawn of the city-county law enforcement building.

James "Nick" Clark, 20, of Logan, was returning to the Cache County Jail from his job at about 9 p.m. Thursday when he saw a man in a pickup truck equipped with a chain trying to pull the cannon from its concrete base, said Cache County Sheriff Sid Groll."Realizing he had been spotted, the man fled, but Mr. Clark pursued the suspect to the parking lot of Albertson's Food Center 21/2 blocks away," Groll said. "Mr. Clark told us he put a `strong-arm' on the man, and brought him back to the Logan police."

Groll said Robert Andrew Miller, 36, of Encinitas, Calif., was arrested and charged with second-degree felony theft. He was released from jail Friday on $1,500 bail and will enter a plea Feb. 28.

Clark has been in jail since August, serving an indeterminate sentence for third-degree theft of firearms, but he might get out sooner.

"I would not be surprised if Adult Probation and Parole decides to shorten his sentence a little because of his action Thursday," he said.
