SDLP West Tyrone representative Daniel McCrossan has called on police to review the way in which they carry out search operations.
He has warned that heavy handed approaches risk losing community confidence.
Mr McCrossan was speaking after a search operation in Ballycolman left two disabled older people left shocked and unnerved.
Police say an assault rifle was seized during the “intelligence-led operation”.
It cam just days after a mortar bomb device was defused in a cemetery in Strabane.
He said: “The PSNI are operating in a very difficult climate and clearly search operations are crucial to disrupting and apprehending those involved in serious criminality.
“However, some of the reports I have received from those who have had property etc. searched have revealed a growing concern at the heavy handed way in which the police carry out these operations.
“Only this week police abruptly searched the home of two people in their late fifties with a range of complex needs.
“Their approach and attitude fell far short of the standard expected when working with vulnerable people.
“I have spoken to the homeowners and their neighbours and it’s clear to me that this community has very valid concern about the character of the operation.
“My party colleague and Policing Board member Dolores Kelly MLA has also raised concerns about the role of the British Army in home searches related to dissident republican activity.
“Having soldiers on our streets does nothing to increase local confidence in policing arrangements.
“The SDLP will continue to pursue this and ensure that the Patten reforms and the primacy of the accountability structures are upheld.
“Confidence in the police is crucial if we’re to tackle criminality in communities across the North.
“The PSNI have a difficult job to do but that doesn’t mean they can ride rough shod over the needs of local people.
“I will be raising this case with local police commanders as soon as possible.”
