The death of a Manhattan jewelry store worker has been ruled a homicide.

Omid Gholian, 43, died from compression of his neck, according to the medical examiner's office.

The Brooklyn resident was found in the bathroom of "World of Gold 'N Diamond" on Church and Duane Street in TriBeCa back on February 15.

Sources tell us he had two zip ties around his neck, but there were no signs of forced entry or anything missing from the store.

Sources also say Gholian had been reported missing by his brother two days before he was found.

No arrests have been made.
