A man visiting friends in the Bronx was instead fatally stabbed in the lobby of a Kingsbridge Heights building, police said.

Three men approached the victim, 28, in the building on Sedgwick Avenue near West 229th St around 11 pm Friday, knifing him multiple times in the thigh before they took off, cops said.

He was rushed to St. Barnabas Hospital, where he succumbed to his injuries.

No arrests had been made by Saturday morning.
