A man who fled to his native Guatemala while facing rape charges in Westchester County has been arrested 30 years later — after being spotted riding his bike to a deli.

Nelson Gustavo Caceres, 51, bolted while out on bail in 1989 to avoid his trial on charges he sexually assaulted a woman in Mount Kisco after she refused to go home with him, the Westchester County Police Department said Monday.

He was convicted in absentia of first-degree attempted rape and sentenced in 1989 to five to 15 years in state prison.

Police believed the Guatemalan national returned to the Central American country to avoid jail — but a recent case review suggested he had returned to New York and was living in Mount Kisco.

“Detectives conducted multiple interviews in the village and set up surveillance at several locations,” cops said in a statement. “Their investigation determined that a person thought to be Caceres frequented a local deli and was riding a red bicycle.”

He was busted Friday night after chaining his bike to a tree to go inside the deli. He was nabbed as he went back to get it.

Police said Caceres will finally serve his sentence — and also faces a felony charge for jumping bail. He was arraigned Monday and remanded to county jail in Valhalla.

“We received a good deal of cooperation in the Mount Kisco community during this investigation and are grateful for the public’s assistance,” Police Commissioner Thomas Gleason said. “Mr. Caceres will now serve the sentence that was handed down three decades ago and the victim in this incident will receive the justice she deserves.”

The top cop said his department never gave up hope in the case, which remained open for the last three decades.

“This open warrant has been investigated on a regular basis for the last 30 years,” Gleason said. “Our detectives will not give up until the offender is brought to justice.”
