‘Boardwalk Empire’ actor Michael Stuhlbarg seen leaving apartment in first public appearance since alleged attack

“Boardwalk Empire” actor Michael Stuhlbarg was spotted leaving his Upper West Side apartment Monday morning — the day after he was allegedly randomly attacked by a homeless man with a lengthy rap sheet.

The 55-year-old actor, who is set to take the stage Monday for the first preview of his upcoming Broadway production “Patriots,” was wearing all black and carrying several bags as he headed out without commenting.

Stuhlbarg will play Russian oligarch Boris Berezovsky in the play, written by “The Crown” creator Peter Morgan about the rise of Vladimir Putin.

Stuhlbarg was walking near East 90th and East Drive Sunday just before 8 p.m. when 27-year-old Xavier Israel allegedly struck him in the back of the neck with a rock, causing an abrasion.

Israel, who is homeless, has previously been arrested for two assaults as well as an attempted robbery, all of which took place in January 2022, police and sources told The Post.

Stuhlbarg was attacked less than 2 miles from where his “Boardwalk Empire” character, Arnold Rothstein, was fatally shot in the popular HBO drama.

His attacker had been on parole for the attempted robbery at the time of the attack.

After Israel allegedly threw the rock at Stuhlbarg, the actor chased him down the block.

The suspect was quickly caught by police stationed outside the Russian Consulate at 9 East 91st Street.

A witness told police she saw Israel pick up the rock and throw it into a crowd of people.

Police charged him with assault. He was awaiting arraignment in Manhattan Criminal Court on Monday.

Israel has a lengthy rap sheet, including several other assaults on random civilians in Central Park.

The 27-year-old was caught on surveillance camera footage in 2022 beating up and stealing the wallet of a good Samaritan who had given him his coat on a chilly January morning, law enforcement sources at the time said.

He was later arrested after pocketing nearly $1,500 from the stranger.

The attack was also the second time in a week Israel had turned on someone trying to offer him help.

Days before, he pummeled a 49-year-old woman who had reportedly been trying to help him. Israel was arrested, charged with assault and released on a desk appearance ticket, sources told The Post.

Israel allegedly assaulted two more victims – a man and a woman – on Jan. 2 inside Central Park, according to sources.

He is accused of randomly punching the 18-year-olds as they sat on a rock inside the green space.

He was also charged with assault in the Central Park incident.

Stuhlbarg declined medical assistance for the reported pain and bruising on the back of his neck, police and sources said.

The Post has reached out to his reps for comment.
