Two boys picked the wrong time to steal the cash donation box at the Moravian Smithy on Wednesday, police said.
Little did they know, two officers from the Bethlehem Police Department's mounted unit had stopped right outside the door of the Smithy, at the south end of Main Street.
After the juveniles grabbed the box around 12:45 p.m., they headed for the door and came face to face with the officers and their horses, George and Pharoah, said police.
The one carrying the cash box saw the police and turned around to hand the cash box back to the blacksmith and said, "Sorry."
The two boys immediately fled the area on foot, running down the embankment to Johnston Park, police said.
The mounted officers followed and called for backup. Within a minute, at least 15 Bethlehem officers flooded the area from Johnston Park to Sand Island.
One of the suspects tried to hide in the Monocacy Creek but couldn't escape and was taken into custody near Conestoga Street by an officer on a mountain bike, police said.
The other juvenile is still at large.
