SANTA FE (AP) — A Santa Fe man who was on bail in a robbery case and wearing a GPS monitoring device has been re-arrested after police used the device to link him two other heists.

Robert Romero pleaded not guilty on Thursday to robbing the same Santa Fe-area convenience store twice last week.

The 24-year-old was first arrested last month after allegedly robbing a pharmacy of 200 Oxycontin pills using a toy gun. He was released on $25,000 bond and required to wear the GPS device.

Sheriff's Lt. William Pacheco tells the Santa Fe New Mexican ( ) Romero was rearrested Saturday for last week's robberies. Court records show the GPS device put him at the store.

Romero's defense attorney said he didn't have enough information to comment about the new charges.
