Derry Hamilton's shirt factory demolition gets underway
Demolition work is under way on the former Hamilton's shirt factory on Foyle Road in Londonderry.
There were concerns about the stability of the building, which has been derelict for years, after the collapse of an internal wall last week.
Contractors began work on Friday night and on the Foyle Road side the building is now down to a single storey.
Foyle Road is closed between the lower deck of the Craigavon Bridge and John Street roundabout.
Some cordons are also in place in John Street.
Motorists are advised to avoid the area and use the Foyle Bridge where possible.
Environment Minister Alex Atwood recommended the demolition in the interests of public safety.
