The personal assistant of a young tech entrepreneur who was found decapitated and dismembered in his Manhattan apartment this week was arrested early on Friday and is expected to be charged in the grisly killing, according to two officials briefed on the matter.

The entrepreneur, Fahim Saleh, 33, was discovered dead on Tuesday afternoon by his sister inside his $2.25 million condo in a luxury building on the Lower East Side, the police said. She had gone to check in on him after not hearing from him for about a day.

She found a gruesome scene: Mr. Saleh’s head and limbs had been removed, and parts of his body had been placed in large plastic bags. An electric saw was still plugged in nearby.

The personal assistant, Tyrese Devon Haspil, 21, was expected to be charged in a criminal complaint with second-degree murder and other crimes.

Detectives believe that the motive for the killing stemmed from Mr. Saleh’s having discovered that the assistant had stolen tens of thousands of dollars from him, despite the fact that Mr. Saleh had not reported the man and had set up what amounted to a repayment plan for him to return the money, one of the officials said.

The police were expected to announce the arrest at a news conference on Friday.

Investigators have also concluded that Mr. Saleh was killed on Monday, the day before his body was found, and that the killer used his employer’s credit card to pay for a car to a Home Depot, on West 23rd Street in Manhattan, to buy cleaning supplies to sanitize the crime scene, the official said. The killer returned to Mr. Saleh’s apartment the next day to dismember the body and clean up.

Detectives believe that the killer, dressed in a black three-piece suit, wearing a black mask and carrying a duffel bag, followed Mr. Saleh off an elevator in his building and into his apartment, a law enforcement official said. He used a Taser to immobilize Mr. Saleh and then stabbed him to death.
