Police in Spain said a pair of suspected shoplifters who fled from store workers were arrested when they returned for their left-behind baby. Investigators said the man and woman were seen in a Barcelona book store Saturday hiding items in their bags and clothing and they fled when the store manager spotted them, but left behind the stroller with their baby, ThinkSpain reported Wednesday. The baby was turned over to police and the couple were arrested when they returned to the store later in the day to ask about their infant.
