A man was punched in the face several times by a brute who shouted anti-gay slurs at him in Brooklyn, police and a witness said Wednesday.

The victim, 43, was walking on Hancock Street near Marcy Avenue in Bedford Stuyvesant around 9 a.m. Tuesday when a man he didn’t know yelled, “F—–g f—-t!”

He tried to ignore the hater and walked away, but the attacker doubled down, yelling, “Yeah I’m talking about you, f—-t!” The attacker then ran up to him and punched him in the face repeatedly before fleeing, cops said.

The victim, who suffered a cut on his nose, refused medical attention.

A man who lives in front of the attack scene said he saw the victim after the attack and that he was conscious and talking.

The assault is being investigated as an anti-gay bias crime.
