A suspect has reportedly been arrested in the decade-old, gang-related murder of a North Bellport teen.

Alvin Brothers, 15, was killed in a drive-by shooting while leaving an anti-crime rally at a park back in 2007.

Trendell Walker, of Patchogue, a known member of the Bloods street gang, has now been charged in the murder, according to Newsday.

Police say Walker has been in jail since 2016 in connection with another shooting.

He is scheduled to be arraigned in the Brothers case on Monday.
