Robert Ryffel, 51, of 91 Blake Drive, was charged with breach of peace around 6:30 p.m. Monday after he frightened customers of Cumberland Farms, 1101 Post Road, who saw a machete sticking out of his backpack, police said.

Ryffel told officers he had been using the machete as part of "volunteer work for the storm," police said.

He was released on a promise to appear Sept. 13 in Bridgeport Superior Court.
