A lifelike baby doll prompted police in New Hampshire to smash a car window in a rescue attempt that turned out to be a false alarm.

Police in the town of Keene said someone called them last month to report an infant left in a car at a shopping plaza on a hot day, WMUR-TV reported.

Lieutenant Jason Short shattered the window with his baton. He told the station he thought he was looking at a lifeless child but noticed something was wrong when he began to breathe into the baby's mouth.

The lifelike doll belongs to a Vermont woman who collects them as a way to cope with her son's death, the station reported. She said police told her they would pay for the broken window.
