Last month, Billboard magazine named Bronx drill rapper Kay Flock its R&B/Hip-Hop rookie of the month for his chart performances.

This month, the 18-year old has been arrested for murder.

According to the police, Flock walked into a Harlem barbershop on December 16.

Upon spotting an opp, Flock pulled out a gun and opened fire.  He hit the victim, who died, in the back and neck.

Flock was wearing a mask during the shooting as Omicron is no joke in NYC.  However, he was still quickly identified and eventually arrested.

He is being charged with second-degree murder in what police are calling a gang-related incident.
