A father was arrested Monday evening after leaving his 5-month-old and 5-year-old sons in a cold, unattended car while he shopped, Suffolk County police said.

Luis Lucero Fajardo, 32, of 73 Wiggins Ave., Patchogue, was charged with two counts of endangering the welfare of a child.

Suffolk police responded about 5:40 p.m. to the Patchogue Village parking lot, 32 W. Main St., to a report of two young children left alone in a vehicle, authorities said. Police said the 1999 Mazda was locked and the engine was not running.

Witnesses said the children had been in the Mazda for 15 minutes before police arrived. The temperature was 25 degrees outside at the time, police said.

Fajardo was arrested when he returned to the car, police said.

He didn't have a driver's license, and his car was uninsured and not supposed to be on the road, police said.

He was scheduled to be arraigned Tuesday in First District Court in Central Islip, but the outcome was unavailable Tuesday night.

The children were released to their mother, said police, who added the Suffolk County Department of Social Services' Child Protective Services Bureau would be notified.
