OPINION

The order denying the Commonwealth’s petition for extension of time for the commencement of trial, pursuant to Pa.R.Crim.P. 1100(c), is reversed. The case is remanded for further hearing and for findings on whether the prosecution exercised due diligence and whether the judicial delay was justified in light of Commonwealth v. Mayfield, 469 Pa. 214, 364 A.2d 1345 (1976).
