A man was stabbed to death outside a Bronx pizzeria Thursday evening, authorities said.

Kevin Smith, 62, was knifed in the lower back just before 7 p.m. in front of Bedford Pizza on Bedford Park Boulevard near Decatur Avenue in the Bedford Park neighborhood, cops said.

An unconscious and unresponsive Smith, who lived less than a block from the pizzeria, was rushed to St. Barnabas Hospital, where he was pronounced dead.

Cops did not have additional details Friday morning on what led to the fatal attack.

No one has been arrested in connection with the slaying.
