Domagoj Patkovic, 31, was arrested in Portland, Ore., on Tuesday and charged  with making multiple bomb threats against Jewish hospitals in New York beginning in May 2021.

“On at least one occasion in September 2021, the hoax bomb threat resulted in a partial evacuation and lockdown of an entire hospital on Long Island,” according to the U.S. Attorney’s Office for the Eastern District of New York. “No explosive devices were ultimately found in any of the locations.”
