A Brooklyn man holed up in the house with his father during the coronavirus outbreak was arrested Wednesday for allegedly knifing and “badly mutilating” his dad, including by disemboweling him, police and sources said.

Following the gory murder, Khaled Ahmad, 26, allegedly left his family’s Dyker Heights home drenched in blood and went to a nearby bagel shop around 4:30 a.m., where he confessed to police officers.

“I killed my father,” Ahmad told them, according to an NYPD spokesperson.

The cops cuffed him and went to the tidy, two-family brick home on 84th Street near 14th Avenue, where they found 57-year-old Imad Ahmad dead with multiple stab wounds, police said.

“The body of the father was badly mutilated,” the spokesperson said.

Ahmad had allegedly cut off his father’s arms and part of his head, in addition to gutting him, police sources said. He had placed some of the body parts near the rest of the corpse.

He told officers that he and his dad had been trying to stay home during the pandemic, the sources said.

Cops found a large kitchen knife inside the house.

A neighbor told cops she’d heard screaming coming from the home overnight but did nothing because it was a “daily occurrence,” the sources said.

A female relative who answered the phone at the house on Wednesday evening told The Post she had no comment, before adding “This is heartbreaking.”

Ahmad was charged with murder and criminal possession of weapon. Police didn’t say what triggered the attack.

A neighbor said the father owned a supermarket in Queens and was “a very good man.”

“They were a very nice family. Very nice people. It is very strange. Very strange,” the 54-year-old said.

The murder was one of four to take place in the Big Apple over less than 12 hours beginning Tuesday afternoon.
