An off-duty NYPD cop was shot by his father, who then turned the gun on himself in a bloody domestic dispute in a Bronx apartment Wednesday, law enforcement sources said.

At least one person was killed in the violent encounter on Fteley Avenue near East 172nd Street in the Soundview section around 12:45 p.m., according to police and the sources.

It is unclear whether the officer or his father died.

A pregnant woman was also hospitalized, according to sources.

The officer, who was not immediately publicly identified, joined the force in 2018 and works in the Narcotics Division in the Bronx, according to sources.

Sources said the cop, who was not immediately identified, was losing a great deal of blood while “hysterical” family members looked on.
