A Brooklyn man was beaten to death by a guy who accused him of stealing, cops said Monday. 

Arthur Fleschner, 60, was gravely wounded when Danny Quiles, 52, punched him several times and knocked him to the ground on Hegeman Avenue near Chester Street in Brownsville around 9:15 a.m. Dec. 4, authorities said. 

Quiles attacked Fleschner because he believed the older man – who he knew from their affordable-housing building about two blocks away – had taken his “personal property,” cops said. 

Fleschner was discovered lying on the sidewalk with head trauma and was rushed to Brookdale University Hospital and Medical Center, where he was pronounced dead four days later, police said. 

Quiles was arrested the next day and charged with manslaughter, cops said. 

He was ordered held on $300,000 bail, with his next court date scheduled for Thursday.

The building where the two men lived on Hegeman Avenue near Amboy Street provides permanent, affordable housing for single adults, according to its website.
