or the illegal keeping, sale or manufacture of controlled substances, as defined in section 1 of chapter 94 C,
or the illegal keeping of a weapon in violation of section 10 of chapter 269, or possession or use of an explosive or incendiary device or other violations of section 101, 102, 102 A or 102 B of chapter 266
or, if a tenant or household member of a housing authority or federal or state assisted housing commits an act or acts which would constitute a crime involving the use or threatened use of force or violence against the person of an employee of the housing authority or of state or federally assisted housing or against any person, while such person is legally present on the premises of a housing authority,
or on the premises of federal or state assisted housing, such use or conduct shall, at the election of the lessor or owner, annul and make void the lease or other title under which such tenant or occupant holds possession and, without any act of the lessor or owner shall cause the right of possession to revert and vest in him, and the lessor or owner may seek an order requiring the tenant to vacate the premises or may avail himself of the remedy provided in chapter 239.
If the lessor or owner is entitled to relief pursuant to this section, such lessor or owner may seek declaratory judgment of his rights hereunder in the district, superior or housing court, which may grant appropriate equitable relief, including both preliminary and permanent injunctions, including a preliminary injunction granting the lessor or owner possession of the premises, and in connection therewith may order issuance of an execution for possession of any such premises to be levied upon forthwith.
No such injunction shall be issued except after notice has been given to the tenant and a hearing has been held with opportunity for the tenant to confront and cross-examine witnesses and to present any legal or equitable defense.
A housing authority or provider of state or federally assisted housing shall not avail itself of the remedies contained herein except after notice, hearing, and decision on the merits by the court.
An appeal from equitable relief granted by a district court pursuant to this section shall be to the appeals court in the same manner as if relief had been granted by the superior court.
