A Brooklyn woman was arrested Wednesday for allegedly stockpiling weapons inside her home.

Police executed a search warrant at a home located at 8699 19th Avenue near Benson Avenue in Bath Beach.

They found more than two dozen weapons including assault rifles, handguns, a grenade launcher and 10,000 rounds of ammunition.

Helen Chin, 53, is now facing multiple counts of criminal possession of a weapon.

Investigators say some of the firearms were registered to her late husband.
