On October 30, 1974, a criminal complaint was filed against the appellant, charging him with robbery, aggravated assault, and other offenses. On September 18, 1975, the appellant was convicted of the charged offenses by a jury. The appellant now claims that he was not afforded a speedy trial under Rule 1100 because he was not brought to trial within 180 days from the date the criminal complaint was lodged against him. See Pa.R.Crim.P. 1100(a)(2). The Commonwealth does not contest that it failed to bring the appellant to trial within the mandatory period, asserting instead that the appellant forfeited his right to a speedy trial under Rule 1100 by failing to comply with the requirements of Rule 1100(f). We agree with the Commonwealths contention.
