The 24-year-old victim was sexually assaulted by Olumuyiwa Olumodeji at a Manila Avenue party Tuesday, Hudson County Prosecutor Esther Suarez said.
Olumodeji is also facing a charge of aggravated assault for trying to cause serious bodily injury to a man at the party who tried to keep him from leaving the scene, Suarez said.
He was arrested at the Jersey City Prosecutor's Office just after 9 a.m. Saturday, authorities said.
