18 Pa.C.S. § 3902

Conduct denominated theft in this chapter constitutes a single offense. An accusation of theft may be supported by evidence that it was committed in any manner that would be theft under this chapter, notwithstanding the specification of a different manner in the complaint or indictment, subject only to the power of the court to ensure fair trial by granting a continuance or other appropriate relief where the conduct of the defense would be prejudiced by lack of fair notice or by surprise.
