Officials say a 19-year-old Brooklyn man stabbed and killed his father at their home on Saturday night.

The NYPD responded to a 911 call on East Third Street just after 10 p.m. on Saturday and found 56-year-old Mohammad Razzaq unconscious and unresponsive with a stab wound to the neck. He was pronounced dead at the scene.

Police arrested the victim's son, Hassan Razzaq, and charged him with murder and criminal possession of a weapon.

An investigation is ongoing.
