Unnotified eviction and removal of personal property of a 15/yr tenant at will senior citizen woman

What legal action can be taken by a victim of unnotified eviction along with removal of personal property in the case of a tenant at will who was absent for travel and paying advance rent until learning from third parties that the lock had been broken and personal property removed. There are complex circumstances including a disputed change of management who changed email address and alleged that the prior management changed the lock at an umspecifiedmtime prior to the arrival of new management who claims to have been uninformed about the prior occupant but found personal property and removed it assuming to have been abandoned by someone unknown to them. I have been on an extended foreign visit and made email reauest state to police to investigate but did not receive report from them, though I am aware they at least questioned the new management, who say they safely stored "whatever they found" in the allegedly prior opened premise which is a studio-type large area, one among several similarly sized small accommodations and many guestrooms, the latter temporarily occupied by travelers; but my large amount of items obviously showed the "unknown occupant" had lived there a long time... i am amsenior cotizen woman, single, somthis situation is auite devastating and i shall need guidance for action. Thank you. UK resident still abroad
