A man was fatally shot on a Williamsburg street corner early Monday morning, authorities said.

The unidentified victim — believed to be in his 30’s—was found with a gunshot wound to his face at approximately 1 a.m. on Bedford Avenue and South 9th Street, cops said.

He was declared dead at the scene.

“I heard loud arguing so I knew something was wrong because it’s normally a quiet block,” said a resident who lives across the street from the shooting.

“About two minutes after [the shot] some guy came back after and took something out of his pocket,” she added.

It is unclear what sparked the gunfire and police are investigating. There have been no arrests.
