HOUSTON -

A 5-year-old was taken on a frightening ride when someone stole his parents' vehicle while he was still inside it.

Houston police said a couple and the child went to a Foodarama in the 11000 block of Fuqua about 9:20 p.m. on Thursday.

The couple left the 5-year-old in their pickup truck, with the keys, while they went inside to buy water, police said.

Detectives said a man got into the vehicle and drove off.

When the thief discovered the child was in the vehicle, he stopped at a Walgreens across the street and ordered the child to get out of the vehicle, police said.

The child, who was not injured, was reunited with his parents.

Investigators have not said if the couple will face any charges for leaving the child alone in the vehicle.

The pickup truck has not been found, police said.
