Tony award winning playwright David Henry Hwang is speaking out after being attacked in Brooklyn earlier this week.

Hwang says he was coming home with groceries Sunday night when he suddenly felt like he had been punched in the head.

He later realized he was bleeding from the neck.

Police say the man in the surveillance photos walked up behind Hwang, stabbed him in the neck and ran off.

It happened on South Oxford Avenue near Lafayette Avenue in Fort Greene.

Police say the attacker didn't say anything to Hwang or try to rob him.

Hwang walked to Brooklyn Hospital, where he was treated and released.

In a statement, Hwang said in part, "I have full confidence that the NYPD is investigating my case vigorously, and will hopefully prevent another such random attack."

Hwang's most recent Broadway play was "Chinglish."

He won a Tony Award in 1988 for his play "M. Butterfly."
