Police are searching for two suspects who robbed a man at knifepoint in Staten Island — and made off with nearly $2,000 in cash, cops said Saturday.

The 20-year-old victim was outside a NYCHA housing complex in Mariners Harbor at about 3:00 a.m. Thursday when two individuals approached and threatened him, police said.

One suspect grabbed the victim from behind, warning him not to move, while the other flashed a knife.

The pair then took $1,843 in cash from the victim’s pockets and fled, police said.

One of the suspects had black hair and a blue hooded jacket, while the other was wearing brown boots and a black sweatshirt, police said.

No arrests have been made and the investigation is ongoing.
