WILKES-BARRE, Pa. - Police say a man looking for cash to replenish his crack supply threatened store clerks with a sharpened barbecue fork and a large kitchen knife during a string of robberies in northeast Pennsylvania.

Timothy Burns was charged Monday with robbery, resisting arrest and aggravated assault on a police officer in connection with a pair of heists in Wilkes-Barre.

The Citizens' Voice reports that police say the 31-year-old is also a suspect in three other robberies.

One of the clerks says the man banged a barbecue fork on the counter, lunged at him and demanded money. The clerk says the man bragged he'd never be caught.

Burns is jailed on $100,000 bail pending a June 25 preliminary hearing.
