The “person of interest” identified in the vicious murder of tech CEO Fahim Saleh is a former employee who was involved in a financial deal gone bad, sources told The Post Friday.

The new details emerged as police continue to hone in on the “person of interest” — described as an ex-worker whose financial agreement with Saleh soured, sources said.

That person is not yet in police custody, sources added.

Saleh was found dead Tuesday in his Lower East Side apartment — decapitated and dismembered, his limbs stuffed into plastic bags, sources said.

A concerned cousin made the grisly discovery, buzzing up to Saleh’s seventh-floor apartment and possibly scaring off the alleged killer.

Saleh was the CEO of Nigerian-based motorcycle ride-hail firm Gokada. The 33-year-old tech whiz was also an investor in Picap, another ride-sharing company in Colombia.

Prior to Gokada, Saleh founded mobile-app developer TapFury, which created popular crank-calling program PrankDial, as well as transportation-focused Pathao in his parents’ native country of Bangladesh.

Two years ago, he launched Manhattan venture capital firm Adventure Capital.
