Famous NBA commentator Mike Breen's home in Long Island was completely destroyed in a massive fire over the weekend ... and officials tell TMZ Sports the blaze is under investigation.
The incident happened on Sunday at 4:03 AM when the Manhasset-Lakeville F.D. received calls from Breen's neighbors ... as well as an alert by the residential automatic fire alarm.
When MLFD arrived on the scene, they "encountered a fully involved house fire."
You can see in a video -- captured by MLFD -- the home was engulfed in flames and the roof of the garage was collapsing in the inferno.
"Numerous hand lines, as well as 2 ladder pipes and a deck gun, were used to battle the fire," officials said.
