A suspect device, which later turned out to be a hoax, has been left outside the home of an SDLP assembly member in Londonderry.
Pat Ramsey said he would not be intimidated
The device was found outside Pat Ramsey's home in Meenan Drive in the Bogside area of the city at about midnight on Saturday.
The Army declared the device a hoax about an hour later. Mr Ramsey has been targeted several times in the past.
Mr Ramsey said the incident caused disruption to the community.
"It is clear that the people responsible for this latest act of intimidation are the same faceless thugs who have attacked my home on countless occasions in the last few years," he said.
"They should know by now that they will not deter me from my political beliefs or pursuing them democratically for the good of all the people of Derry."
Meanwhile, a separate security alert in Newtownhamilton, County Armagh, has ended.
Army technical officers were called to examine a suspicious object found in Newry Street on Sunday morning, but it turned out to be a false alarm.
