A Brooklyn man has been arrested and charged with murder for gunning down an exotic dancer in Gramercy Park on Thursday, sources said.

Clarkson Wilson, 44, who fathered at least one of Imani Armstrong’s three children, is accused of lying in wait for the young mom as she headed home from a second job at IHOP.

Armstrong was gunned down at 5 a.m. Thursday by a killer who snuck up behind her on East 14th Street and Irving Place and shot her in the head, authorities said.

Wilson, who has more then 20 arrests on his rap sheet, was also charged with two counts of criminal possession of a weapon, the sources said.

It’s unclear what sparked Armstrong’s murder, but an acquaintance of the young mom told The Post Wilson had been seen around the IHOP where she worked and knew her routine.

Armstrong told friends Wilson was “her baby’s daddy,” the acquaintance said, adding, “he  seemed weird. He has been lurking around for sometime now – at least early August.” 

Wilson was last spotted two weeks ago in the morning hanging around, acting erratically and scaring people.  

“When confronted, he said he was waiting for somebody,” the acquaintance said.

Wilson has at least four prior complaints against him for alleged domestic violence stretching back to 2014, the sources added.

It was not immediately clear if any of the domestic violence complaints were made by Armstrong.

In April 2021, a woman accused Wilson of choking her after they began to argue, the sources said.

In Sept. 2014, Wilson’s then-wife told authorities he took her phone, choked her and pushed her into a wall. At the time, Wilson was living with his wife and her mother, the sources said.

Wilson was hauled into the 13th Precinct stationhouse on East 21st Street Saturday morning for questioning in Armstrong’s killing, the sources said.

The Regional Recovery Task Force in Brooklyn, armed with a search warrant, took Wilson into custody, the sources said.

Wilson’s arraignment was pending Saturday. 

At about 2:30 p.m., two detectives flanked the murder suspect as they emerged from the stationhouse. Wearing black shorts, red and black Jordan basketball shoes, and a black Street Fighter shirt, Wilson did not respond to reporters’ questions about why he allegedly killed Armstrong. 

As he was escorted into a black Ford sedan, he kept his eyes toward the ground almost the entire time, looking up at reporters once just before entering the car after they had shouted Armstrong’s name multiple times.
