A landlord cleaning out a deceased tenant’s apartment in Manhattan this week found a stash of weapons, including crossbows and ninja swords, police sources said.

The landlord was inside a sixth-floor apartment on 215th Street near Seaman Avenue in Inwood around 2:50 p.m. Wednesday when he made the shocking discovery of two fake grenades, two rifles, a machine gun, a machine pistol, an airgun, two crossbows, two ninja swords, a flare gun and ammunition, according to the sources. He called 911 after finding the stash, cops said.

The weapons — which were vouchered at the 34th Precinct station house — are believed to belong to the tenant, according to the sources.
