Bethlehem, Pa. ? As Lehigh University students prepared for final exams this week, they found themselves grappling with the news that the sophomore class president had been arrested for allegedly robbing a bank.

“I didn’t believe it when I first heard it,” Kathryn Susman, an 18-year-old freshman engineering student from Hereford, Md., said Monday.

The robbery occurred Friday afternoon. Authorities said Greg Hogan, 19, handed a note to a teller at a Wachovia Bank branch, saying he had a gun and wanted money.

Hogan, the son of a Baptist minister, was picked up at his fraternity house later that evening and charged with robbery, theft by unlawful taking and receiving stolen property.

Police said he got away with $2,871.
