Authorities are looking for four people who carjacked a vehicle near the Rutgers University campus in New Brunswick early Monday. The carjackers showed a weapon to the driver near the intersection of Nichol Avenue and Sandford Street at 12:50 a.m., Rutgers police said. The four carjackers then ordered the driver out and fled in the vehicle. Police said the victim — who is not a Rutgers student or university employee — was uninjured. The carjacking took place just off the Douglass Campus at Rutgers.
