Lee County Sheriff's Office leaving an unlocked bicycle near Fort Myers Middle School as part of an undercover sting following a recent spike in thefts in the area.

Two 12-year old kids were arrested Thursday and charged with petty theft after making off with a bike.

The parents of one of the children say the kids were taking the bicycle back when they were caught.

"What bothers me is how they handled it. I'm not trying to stop them from doing their job. I'm just upset over how they did it. Its practically right down the street from his school," said the father of one of the children.

The Sheriff's Office says they don't have to notify parents immediately if the child is being arrested.
