Delray cops getting clever with bike thieves

Read this from the Sun Sentinel how the police in Delray are handling bike thefts:

After a surge of bike thefts in Delray Beach, police left an unlocked bike against a tree Monday and waited for someone to steal it.

Police said they put an electronic surveillance device in the bike left on the 100 block of South Ocean Boulevard and waited. Then at 8:05 a.m., an alert told police the bike was moving.

[and...]

Police said the bike is valued at $189.76 but due to the $450 surveillance device inside, the total value of the theft is raised to $639.76, landing Pierre with a grand theft charge.

I know that our local PBSO uses decoy bikes, but not sure if they employ the surveillance device or not.
