A Brooklyn landlord was found nearly beheaded Tuesday, and police arrested one of his tenants Wednesday on murder charges.

Mahuddin Mahmud, 57, was discovered in the basement of the building he owns in the Kensington section of Brooklyn with his head almost cut off, police told NBC New York. Rasel Siddiquee, 27, was arrested at John F. Kennedy International Airport in connection with Mahmud’s death.

Mahmud’s face was also burned, the NYPD told NBC New York. The Bangladeshi native’s body was discovered by his brother, Mabil Mahmud. A basement safe was opened and $20,000 was missing. New York 1 reported that Mahuddin Mahmud’s throat was slashed.

"I saw my brother's dead body. He don't [sic] move," Mabil Mahmud told WABC. "I say, 'Oh, my God, oh, my God, my brother, my brother.'"

Siddiquee lives in the building’s basement, CBS New York reported. He was charged with second-degree murder and criminal possession of a weapon.

Mahuddin Mahmud was the father of three, including two boys, ages 9 and 4. Neighbors told WABC that the slain landlord was kind to the community. His family and friends said to NBC New York that he came to the United States decades ago to start a computer software training business.

"I knew this gentleman in the community, very helpful. This is unfortunate," said neighbor Mian Maniky. "We're just trying to comfort the community and the family."
