Boy enters bus barefoot, driver immediately calls the police

At the station   

The officer on duty listened to the boy carefully. Margaret added his story here there. The officer asked if the boy wanted a cookie. He said yes. The officer got up and motioned for Margaret to follow. On the way to the cafeteria, he thanked the Good Samaritan.

The officer assured Margaret that she could go back to work and leave the boy to the police. But her statement had to be taken first.
