Authorities have arrested two people in the slaying of an off-duty Newark police detective who was gunned down earlier this week during a robbery in Paterson.

Detective Michael Morgan was killed early Monday outside a nightclub where he was celebrating a friend's birthday. Officials say the 32-year-old was walking a dancer from a gentleman's club to her car when they were confronted by an armed robber. Police say Morgan was shot once in the torso after he reached for his weapon, which was found under his body.

Morgan had worked for the Newark Police Department since 2005. He had just been promoted from the narcotics and gang unit to special investigations.

Prosecutors say the two arrested are a man and his girlfriend. Both face felony murder, robbery and weapons charges.
