An individual with a history of criminal offenses, Marvin Dupree, was arrested for stabbing a teenager in the neck near City Hall and then smiling menacingly at the victim, as reported by the police on Thursday.

The incident occurred when Dupree, described as a smirking maniac, approached Brooklyn College student Alan Ryvkin from behind and stabbed him in the neck around 11:30 a.m. while Ryvkin was waiting outside a Centre Street building to address a vehicular summons.

After the attack, Dupree was apprehended by the police in Harlem and charged with felony assault.

Ryvkin recounted that he was conversing with a woman outside the building at 1 Centre St. when the assailant silently approached him from behind and attacked him with a knife.

Ryvkin stated, “When he walked away, the dude looked at me and smiled with the knife in his hand. I didn’t know who it is. I don’t know what it is. I got stabbed and I sit on the ground and start bleeding out.”

Sam Townsell, a bartender at the outdoor Jury Duty bar, witnessed the injured Ryvkin being taken away in an ambulance.

Medics transported Ryvkin to Bellevue Hospital where he received treatment for the stab wound.

Following his arrest, Dupree was also taken to Bellevue for undisclosed reasons.

Dupree has a history of arrests for various offenses including assault, aggravated harassment, drug possession, and resisting arrest. He has served time in prison for criminal activities.
