A career criminal was busted in a trio of break-ins at Manhattan businesses — just weeks after being cut loose from prison on good behavior, police said.

It didn’t take long for convicted burglar Robert Candidus, 51, to allegedly go back to his old ways following his release on parole on Jan. 25, according to cops and prison records.

A little over four weeks later, the serial thief allegedly broke through the front window of Ajisai Sushi, a Japanese restaurant on Lexington Avenue, near East 62nd Street in Lenox Hill on Feb. 27. He snatched an unknown amount of cash in the heist, police said.

Candidus allegedly struck again on March 14, smashing through the front door of Flowers by Philip, an Upper East Side florist on Lexington Avenue near East 88th Street — and grabbed $400 from the cash register, according to cops.

Two days later, Candidus was arrested breaking into, Lilli & Loo, a Chinese restaurant on Lexington Avenue near East 61st Street in Lenox Hill, through the front door and snatching $410 from the register, police said.

The ex-con was charged with three counts of burglary after the March 16 bust, according to court records. He was ordered held on $10,000 bail at his arraignment in Manhattan Criminal Court.

Candidus was released from Mid-State Correctional Facility after serving four and a half years of a seven-year sentence for a third-degree burglary conviction, according to the state’s Department of Corrections.

His parole was set to expire in September.

The convicted thief has been sent to prison three other times dating back to the mid-1990s for burglaries and an attempted grand theft auto, state records show.
