Reynaldo Nieves, of Cushing Road in Camden, is charged with aggravated sexual assault, robbery and weapons offenses.
Camden County investigators say Nieves lured a woman to a vacant building on Broadway, forced her inside at gunpoint and sexually assaulted her.
It happened last Wednesday, April 2nd.
Nieves was arrested the next day. He's being held on $500,000 bail.
Investigators now believe Nieves has targeted other women, including prostitutes and other women with a transient lifestyle, and are urging them to come forward.
Anyone with information is urged to contact The Camden County Police Special Victims Unit at 856-757-7042.
