(1) While armed with a dangerous weapon, as defined in 14 V.I.C. § 2251, other than a firearm, uses force or threatens the use of force upon any person or persons within such dwelling place, whether or not injury occurs; or
(2) Intentionally causes any injury to any person or persons within such dwelling place; or
(3) While armed with a firearm uses force or threatens the use of force upon any person or persons within such dwelling place, whether or not injury occurs; or
