Police are investigating the break-ins of three unlocked cars last week with loose change taken but credit cards and other items left behind.

The break-ins of two cars on East Maple and Hoyt streets were reported shortly before 9 a.m. Aug. 10, New Canaan Police Lt. Jason Ferraro said.

The owner of the East Maple Street vehicle said it was left unlocked the night of Aug. 9 and the driver’s side door was found open the next morning, Ferraro said. An estimated $7 in quarters was taken, but two foreign coins were left behind, Ferraro said.

The Hoyt Street car owner reported the glove box, center console and other parts of the vehicle were rummaged through, but only spare change was taken, Ferraro said. A GPS device, driver’s license, and credit cards were not taken, Ferraro said.
