The marketing director of Hudson Regional Hospital had a large cache of guns inside of a closet at the hospital, according to Secaucus police.

Reuven Alonalayoff, of Elmwood Park, was arrested on Sunday at Newark Liberty International Airport. He is now facing multiple weapons charges.

The weapons were discovered last month while officers were doing a sweep of the hospital following a bomb threat.

Police say the hospital received a threatening call on July 18. As bomb detection dogs were doing a sweep of the hospital, one located an unlocked closet within an office. Police discovered 11 handguns and 27 rifles and shotguns. Police say they also recovered a “Kriss Vector .45 caliber semi-automatic rifle with a high-capacity magazine,” and a 14-round high-capacity handgun magazine.

“The unsecured storage of a large cache of weaponry, especially in this location, certainly creates a risk to public safety,” said Chief Dennis Miller said in a statement. “I commend the efforts and professionalism of all the police personnel involved in this investigation and am thankful this situation was resolved without anyone being harmed.”

The bomb threat was later revealed to be a hoax.
