Yoko Ono scared by Dakota building intruder

Yoko Ono got a fright last week after a Korean tourist wandered into her apartment building at The Dakota — where John Lennon was murdered 30 years ago — and rode down an elevator with her, according to published reports Thursday.

The ex-Beatle’s widow told the building’s concierge, who called police, and Sungno Kim, 24, was arrested and charged with criminal trespassing.

The Manhattan district attorney’s office said Kim allegedly entered the Upper West Side building on Jan. 12 through a service entrance and rode the freight elevator up. Published reports said he was trying to take photos from the famous building’s roof.

The charges will be dropped if Kim isn’t arrested within six months and completes one day of community service. It was unclear Thursday whether he had completed that day yet.

Lennon was fatally shot outside The Dakota by Mark David Chapman on Dec. 8, 1980.

Reps for Ono, 77, didn’t return requests for comment.
