Officers soon responded, but the alleged assailant had fled in a cab.
But police say Walsh, who lives in a township motel, had gone there to buy cocaine from Thomas M. Sexton, a 23-year-old Lower Township resident. When he realized Sexton had sold him crushed sheetrock, he made the robbery report.
Sexton was charged with distribution of imitation drugs, while Walsh was charged with wandering in a public place to purchase drugs. And more charges may be filed.
Neither man returned phone messages on Saturday, and it was not known they had retained lawyers.
