A 31-year-old man was busted for allegedly stabbing his sister’s boyfriend nearly a dozen times during an argument on Staten Island Sunday night, police said.

Jonathan Archille was charged with attempted murder, two counts of assault and criminal possession of a weapon after cops found him standing with a knife at a Mariners Harbor home where the violence occurred, police said.

Archille allegedly knifed his sister’s 32-year-old boyfriend 10 times, critically wounding him at around 11:35 p.m. on Mersereau Avenue near Christopher Street, cops said.

The attacker’s 34-year-old sister suffered a slash wound to her right hand as she tried to break up the melee, according to police.

Emergency responders rushed the victim to Richmond County Medical Center where he was listed in critical but stable condition.

Archille’s sister was also taken to the same hospital where she was treated and released.
