NEW: Undocumented immigrant urinating in public used a box cutter to repeatedly stab a man who'd merely suggested he pull up his trousers and use a proper restroom, police say.

Happened Nov. 30 at the Wheaton Metro bus stop.

Per @ICEgov, 46yo suspect is El Salvadoran national. pic.twitter.com/7owFfSeRyk
