Two Asian-hating teen pals, one the stepson of a cop, have been busted for robbing and brutally beating and strangling a Chinese newspaper executive, police said today.

Corey Azor, 16, of Queens, and Chris Levy, 17, of Harlem – who targeted other Asians before – were arrested in with the murder of David Kao, 49, whose body was found Saturday in Flushing.

After the slaying, they said they went joy riding in Kao’s car for two days.

Kao, who lived in Elmhurst, was a marketing executive at World Journal, the largest Chinese-language daily newspaper in the U.S.

His 21-year-old daughter attends college in Taiwan.

“He’s a humble guy who brings happiness too everybody,” coworker James Yam said of Kao.

The teens, who met in junior high school, were charged with second-degree murder, first- and second-degree robbery, and criminal possession of stolen property.

They face 25 years to life if convicted.

They are expected to be charged with using similar tactics to rob another Asian man last month.

Friends said Kao had eaten at a Korean restaurant with a friend Friday evening.

He was dozing in the driver’s seat of his sister’s 2000 Lexus SUV, which was double-parked in front of his ex-wife’s Flushing home when the thugs spotted him at 1 a.m. Saturday, police said.

Azor – whose stepfather is assigned to NYPD’s automotive unit – and Levy broke into the car and put Kao into a choke hold and then dragged him into the back seat.

“I continued to hold him in the headlock and punch him in the face and then he stopped moving,” court papers quote Levy as telling detectives.

The deadly duo callously dumped his body on the street, emptied his wallet of cash and spent the next two days joy riding with a gaggle of teen friends, prosecutors said.

They were busted on Monday.

Yam said coworkers tried to call Kao on his cell phone Saturday after he didn’t show up to play badminton. After that, they called cops.

Cops said Azor later confessed that that he, Levy and 17-year-old Keron Wilthshire robbed Jin Tong Yuan of $60 and his cell phone on May 27.

They followed the victim into the elevator of a Flushing building and when he tried to run, Wiltshire put him in a headlock and Levy held a silver pistol up the Yuans head, police said.

Wiltshire later claimed it was toy gun.

The robbery was captured on a surveillance camera and the images used to track down the suspects, police said.

Azor, a student at Flushing HS, and Levy, a tenth grader at Robert Kennedy HS, were held without bail in Kao’s brutal murder.

Wilthshire, who attends Bryant has a prior assault arrest on his rap sheet, was held on $75,000 bail in the Yuan robbery, for which he was charged with first- and second-degree robbery and third-degree criminal possession of stolen property.

Queens District Attorney Richard Brown called Kao’s slaying a “senseless and brutal crime” that shows “complete disregard for human life.”
