'A small number' of landlords have been trying to carry out illegal evictions of tenants during the Covid-19 outbreak, according to Threshold.
Threshold CEO John Mark McCafferty says attempted illegal evictions by a small number of landlords continue to be a concern.
Mr McCafferty says: "We have had reports of certain renters under pressure because of illegal evictions or attempted illegal evictions by a small number of landlords.
"That continues to be a concern."
