ECONOMY — A school bus driver in Beaver County says he told students he was an undercover officer so they wouldn't misbehave on the bus. They didn't.

But the real police in Economy say what 59-year-old William Dunn did was wrong and charged him with impersonating a public servant.

Police say Dunn flashed a badge and identified himself as an undercover officer to at least three people on Feb. 5.

Dunn says a fellow bus driver had been harassed by students, and he was driving her route that day.
