The New York City Medical Examiner's Office has ruled the death of a Bronx man as a homicide, leading to an inquiry into a failed drug bust operation.

Last week, Eric Duprey allegedly attempted to evade law enforcement on a motor scooter during an undercover operation near the 50th Precinct.

Based on information obtained from law enforcement authorities and surveillance footage, it has been established that Duprey was traveling along Aqueduct Avenue when he was struck in the head with a cooler by NYPD Sgt. Erik Duran, causing Duprey to lose control of his scooter and collide with a parked car.

Duprey was pronounced dead at the scene.

Subsequent to the incident, Duran was suspended without pay. Friends and family members of Duprey are now demanding Duran's arrest.

NYPD officials say that they are actively continuing their investigation into the matter.
