JEFFERSON COUNTY - It's happened more than three dozen times in the last two months at gyms around the Denver metro area.
People come out to their car to find their valuables stolen.
The Jefferson County Sheriff's Office says on the afternoon of Feb. 6, two break-ins were reported at the Bally Total Fitness on Bowles near Wadsworth.
They released photos of a dark colored SUV that had two men inside watching people coming and going from the gym who broke into the vehicles.
The sheriff's office says these latest break-ins may be part of a criminal ring. In most of the cases over the last two months, the car window was broken to steal a purse and the thieves used a drive-thru window at a local bank to withdraw cash using the victim's ID.
