There's an email going around, supposedly from the Harris County Precinct 5 Constable's Office, that people are hanging out in parking lots and giving away key rings with tracking devices in them.
The email states that a "syndicate of criminals (are) presenting themselves as sales promoters" and the "key holders are very beautiful and hard to resist."
According to the email, the "key ring has a tracking device chip which allows the criminals to track and follow you."
Harris County Precinct 5 Constable's Office officials said it's just another version of a hoax email.
According to snopes.com, the hoax has been going on since 2008. Snopes' website states that it began when there was a distribution of flashing key rings at a South Africa gas station. Those key rings did not contain tracking devices and were simply a promotional item for Caltex, a gasoline retailer that is part of Chevron.
