A car thief hopped into an idling Acura parked outside a 7-Eleven on Long Island on Friday morning and zoomed off — before realizing an 8-year-old girl was inside, police said Friday.

The girl’s father had driven up to the Bay Shore Road convenience store with her in the back seat around 7:20 a.m. and left his daughter in the 2007 vehicle while he went inside, Suffolk County police said in a news release.

The thief, driving a red van, soon pulled into the parking lot, got out of his car entered the Acura and drove off with the child in tow — a crime caught on surveillance tape, cops said.

Shortly after, the thief dropped the child off in the parking lot of West Islip Hot Bagels on Hunter Avenue before fleeing in the stolen car, police said.

The child was not injured and was reunited with her dad shortly after.

Cops are still hunting for the thief and the Acura.
