A 14-year-old Wrentham boy tried to buy lunch at King Philip Middle School in Norfolk with a counterfeit $20 bill late last month, police said. Police ended up discovering a second $20 bill on the floor in a school hallway, and two more were discovered in the school district’s bank, where they had apparently escaped detection when deposited, said Norfolk Police Lieutenant Jon Carroll.

A school cafeteria worker on Thursday, Janu­ary 28 reported the phony $20 when the boy tried to use “She said it was just very faded and thin and did not look like a regular bill,” Carroll said. Police are investigating, and the federal Secret Service has been contacted, Carroll said.
