A couple was sitting on a bench in the middle of Union Square at about 5:45 p.m. Saturday when a drunk man unzipped his pants and started urinating on the sidewalk, according to a police report.

The boyfriend, sitting outside 61 Union Square, asked the man to stop exposing himself and peeing in public, the report says.

In response, the man finished urinating, "moaning loudly" as he did, then wiped his hands on the boyfriend, according to the report.

The boyfriend pushed the man, identified as Juan Deleon-Carpio, 51, of 9 Washington St., away, and at this point Deleon-Carpio pulled a pocket knife from his pocket and waved the blade in front of the couple, the report says.

The couple walked away and called police.

Police arrived and handcuffed Deleon-Carpio. He was charged with assault with a dangerous weapon and indecent exposure.
