Authorities have arrested one man in connection to the shooting death of Carey Gabay, an aide to Gov. Cuomo who was killed last year before the West Indian Day Parade.

On Sept. 7, 2015, Gabay was fatally shot on a Brooklyn street while walking with his brother around 3:40 a.m., CBS2 reported. He died on Sept. 15.

On Friday, Queens resident Micah Alleyne, 24, was arraigned on charges of murder, reckless endangerment and weapons possession, the New York Daily News stated, adding that Brooklyn DA Bureau Chief Ken Taub said that Alleyne was just the first arrest as authorities rounded up several others in connection to the stray bullet homicide.

"As I have said from the beginning, we are determined to get justice for Mr. Gabay and his family. And we will continue to press forward until we hold everyone responsible for his death accountable," Brooklyn DA Ken Thompson was quoted by the Daily News.

Gabay, who was educated at Harvard and served as first deputy general counsel at the Empire State Development Corp., has had a portion of Brooklyn’s Clinton Avenue renamed for him, CBS2 added.

"Carey Gabay was an exemplary public servant who lost his life in a senseless tragedy," Gov. Andrew Cuomo was quoted by CBS2. "Today’s arrest is a major step forward in the pursuit of justice for Carey’s family and loved ones."

Alleyne was previously arrested for a 2014 assault, a source said to the Daily News.
