Mayor hurried back from Fla.

MAYOR DE Blasio cut short a vacation to Florida after a veteran firefighter was killed in a Harlem blaze Thursday night.

Hizzoner had jetted off Thursday evening, not long after restaurateur Harendra Singh testified that he’d given de Blasio campaign donations as bribes and had told him of his plans to use straw donors.

De Blasio had plans to catch a Red Sox spring training game in warmer climates — but just hours after he left the city, firefighter and father of four Michael Davidson, 37, was killed in the basement of a St. Nicholas Ave. building that was home to a movie set.

De Blasio has been criticized for being absent from the city during times of tragedy in the past.
