A man has been busted in connection to an unprovoked assault that left an Asian man unconscious in Manhattan months ago, cops said Friday.

Javel James, 42, was arrested Thursday in Brooklyn for allegedly punching the 56-year-old victim as he entered the F train station at East Broadway and Rutgers Street around 8:50 p.m. March 2, police said.

James continued beating the victim even after he fell to the ground and hit his head, police said.

The victim was left unconscious with a cut on his lip, a black eye and swelling to his head, authorities said. 

James, of Queens, was charged with assault, police said. He did not immediately face a hate crime charge. 

The attack came amid a wave of attacks on Asian victims across the city and elsewhere.
