It happened on the 300 block of East Main Street in Newark late Thursday night.
Police say an 18-year-old man and a 21-year-old man were inside their apartment with a guest when they heard a knock on the door.
When they opened the door, the suspect flashed a gun and ordered all three men on the sofa while another suspect ransacked the bedroom before fleeing.
No one was hurt, but the suspects are still on the loose. Police say the victims were not University of Delaware students.
