A man in a ski mask tried to play a prank on a resident assistant in Arizona-Sonora Residence Hall, 910 E. Fifth St., early Friday morning, reports stated.

When police arrived around 3:30 a.m., the RA said he had gotten a knock on his door.

The RA said he looked out the peephole and saw a man in a ski mask with a trashcan filled with water propped up against the door.

The RA said in January a similar incident had happened to him. The RA had opened the door and the trashcan had tipped over, spilling several gallons of water all over his room.

The RA said this time he called another RA and together they removed the trashcan and dumped out the water.

The RA said he tried to find the man who had put the trashcan there. The RA saw a man with a ski mask propped on his head in the sixth floor study lounge.

The RA said, “”Do you think you’re funny?”” and asked the man what his room number was.

The man then got up and left the floor, and the RA did not see him again.

The RA said he could not be positive that the man in the ski mask and the man in the study lounge were the same person, reports stated.
