A 17-year-old boy was arrested Wednesday and charged with murder over a shooting last year at a Brooklyn Sweet 16 party that left a woman dead and six other people wounded, police said. 

The unidentified minor was allegedly among multiple gunmen who opened fire during the celebration inside a building on Albany Avenue near Fulton Street in Bedford-Stuyvesant last November, according to cops. 

Dayjionna Long, a 20-year-old visiting from Virginia, was fatally shot in the hail of gunfire. 

Six other victims, ranging in age from 14 to 19, were also struck by bullets. 

Police have said the deadly gun violence may have been retaliation for a nearby shooting where a reputed 17-year-old gang member was injured. 

It’s believed the gang member attended the Sweet 16 party when it started in East New York. The bash then relocated to the Bedford-Stuyvesant building after police broke it up, sources have said.
