The New Brunswick and Rutgers University police departments are investigating three early morning robberies in the city.

Police said in the 1:13 a.m. incident, an individual was approached by two men on Morrell Street between Sicard and Wyckoff streets.
The men, one of whom was brandishing a gun, demanded unknown items from the individual.
Police said the robbers were described as two African-American men, one with a heavy build wearing a black jacket and a second with a beard and a slim build.
