Four people, including two children, were stabbed to death inside a Brooklyn home, police said.
Cops discovered the bloodshed after they were called to a home near Avenue P and West 8th Street in Bensonhurst around 10:18 p.m. for an assault in progress.
They found a woman, 56, stabbed multiple times in the neck along with a boy, 4, and a 5-year-old girl, authorities said.
A fourth victim, a 27-year-old woman, was found nearby with multiple stab wounds.
The victims were pronounced dead at the scene.
A man, 24, was arrested in connection with the horrific crimes, which investigators believe was fueled by a domestic dispute, authorities said.
The investigation is ongoing.
