Story highlights A spent bullet fragment was found a few blocks from Muhiydin Moye's body, police say

Moye's arrest went viral after he tried to snatch a Confederate flag from a protester

(CNN) A Black Lives Matter activist who rose to prominence after the South Carolina State House Confederate flag controversy was killed in New Orleans while riding his bike late at night, police said.

An officer -- responding to a call of shots fired, which was upgraded to a call of aggravated battery by shooting -- arrived about 1:24 a.m. Tuesday in the city's Gravier neighborhood and found Muhiydin Moye on the ground bleeding, about two blocks from University Medical Center, according to an incident report

Moye, whose February 2017 arrest video went viral after he tried to snatch a Confederate flag from a protester in downtown Charleston, was later pronounced dead at that hospital, police and his family said.

His body was found on a largely residential street, in front of an auto repair shop. His mountain bike, its right side "covered in blood," was found across the street, the report said.

Moye runs on camera during a live broadcast last year.

The officer found a circuitous blood trail that led from Moye's body to a spent bullet fragment in a grassy area four or five blocks away, the report said, adding that there are cameras near the location of Moye's body and near the bullet fragment's location.
