A Chinatown landlord who bitterly spoke out against crime after the high-profile murder of one of his tenants brutally beat an apparent homeless man holding a makeshift weapon Saturday, according to prosecutors and police sources.

The landlord, Brian Chin, 32, was charged with felony assault for the late-night attack that left the vagrant hospitalized with injuries so serious that he was unable to tell investigators his own name, sources said Sunday. 

A police source said the beaten man would be charged with menacing for his role in the fight, which started around 8:30 p.m. near Chrystie and Grand streets in Manhattan.

The homeless man was sleeping on the corner when Chin allegedly slipped on black gloves and then kicked the unidentified victim three times, according to a criminal complaint.

The vagrant woke up and picked up several items before Chin and he appeared to go their separate ways.

But a few minutes later, both men returned to the same location.

Police sources said CCTV video taken from the scene shows the homeless man breaking a wooden chair and then menacingly wielding a piece of the wood at Chin.

The makeshift club had a nail at the tip, a police source said.

The homeless man then appeared to swing the weapon at Chin in the video.

Chin charged the man, knocking him to the ground and punching him in the head over and over again, while also appearing to kick him.

He allegedly slugged the homeless man’s face and head six times before the man laid on his back, not moving, the complaint states.

Blood gushed from the unidentified man’s face as he struggled to get to his feet when authorities arrived, according to the complaint. When the homeless man tried to stand up, he fell backward and hit his head against the subway station railing.

The vagrant was rushed to Bellevue Hospital with multiple facial fractures and a skull fracture, the complaint states.

He remains intubated and on a ventilator as of Sunday afternoon.

Chin, who is cooperating with cops, told police the homeless man had been harassing people before Chin kicked him, according to the source.

The source suggested the landlord might be traumatized after one of the tenants at his Chinatown apartment building was fatally stabbed by a random sicko in 2022.

In that killing, beloved Chinatown creative producer Christina Yuna Lee, 35, was followed home by Assamad Nash, 27, and stabbed 40 times in her own kitchen. Nash pled guilty last month to the murder.

Chin spoke to The Post after a memorial for Lee was vandalized shortly following her murder, saying he and the Asian community are “tired of being attacked.”

The landlord was released on his own recognizance on the assault charge Sunday and is set to next appear in court Oct. 10.
