The enraged husband who beat a man to death with a tire iron for trying to rape his wife inside their Bronx home has been arrested and charged with manslaughter, police said.

Mamadou Diallo, 61, came to his wife’s rescue at their Claremont Village apartment building shortly after 9:30 p.m. Monday after the terrified woman called him to tell him she had just broken free from an intruder who attacked her, cops said.

The attacker, identified as 43-year-old Earl Nash of Foxhurst, broke into the home on Washington Avenue near East 168th Street and hit the woman in the face, causing bruises to her forehead, before ripping off her clothes, police said.

Diallo’s wife of 20 years, Nene Gale, 51, “thought it was her [16-year-old] son knocking on the door so she opened the door and saw the man she did not recognize,” said Diallo’s brother Ibrahima Diallo, 52.

“She went to shut the door and the guy pushed in the door and then punched her,” said Ibrahima, recalling what a shaken Gale told him.

Nash, who has a lengthy rap sheet dating back to 1997, hit the woman in the face, causing bruises to her forehead, before ripping off her clothes, police said.
