A Brooklyn teen was fatally stabbed in a Domino’s pizzeria in an apparent gang attack, cops said Wednesday.

Dashawn Cameron, 18, was inside the pizza joint on Pitkin and Miller avenues in East New York around 9:45 p.m. Tuesday when six men entered the store and jumped him, according to police.

One of the suspects stabbed the victim repeatedly, cops said.

The bloodied teen lay in the shop as emergency responders rushed to the scene.

Cameron was taken to Brookdale Hospital, where he was pronounced dead on arrival, cops said.

The teen lived just a few blocks away from the pizza parlor, authorities said.

One 25-year-old man was in custody and being questioned Wednesday night, but his name was not released because charges were pending, authorities said.

Investigators believe that the knife attack was gang-motivated. The victim had a record of six arrests, four of which are sealed, authorities said.

The other two were for pot possession and jumping a subway turnstile, sources said.
