Hardline republicans in Derry are planning to send letters to shops and businesses in the city urging them not to serve members of the PSNI.
The 32 County Sovereignty Movement has told the 'Derry Journal' it has drawn up a list of businesses and a number of schools in the city who deal with the police and will be contacting them shortly.
According to today's 'journal' the group says letters will be sent to the selected premises highlighting what they describe as the "unacceptable behaviour" of the PSNI.
A spokesperson for the group said if their request for businesses to shun members of the PSNI is ignored, they will stage pickets and "name and shame" shops.
The spokesperson insists that the letter "is not a threat" and will be circulated to shops in the coming weeks.
The spokesperson also said they have been contacted by workers who had concerns about serving police officers.
Foyle MP Mark Durkan has described the group's action is an appalling step.
He says it is the 32 County Sovereignty Movement threatening people once again and a return to the old, futile, sterile Provo-speak of the past.
