‘Boardwalk Empire’ actor Michael Stuhlbarg was randomly attacked with a rock by a homeless man near Central Park on the Upper East Side Sunday night, police said.

The 55-year-old was walking near East 90th and East Drive around 7:45 p.m. when 27-year-old Xavier Israel struck him in the back of the neck with a rock, causing an abrasion, police said Monday.

Israel, who is homeless, has previously been arrested for two assaults as well as a robbery, all of which took place in January 2022, police and sources said.

Following the attack, Stuhlbarg chased after Israel, who was quickly apprehended by police stationed outside the Russian consulate at 9 E. 91 Street. Israel was taken into custody without incident and charged in the assault, police said.

Stuhlbarg declined to receive medical assistance, police said.
