As yet the cause of the closure and police activity has not been made public.
The road is closed to vehicles and pedestrians, as is the alleyway through to Upper Priory Street.
Police have also been seen searching bins in the Drapery shortly after 6pm - it is not known if this is related to the St Georges Street incident as yet.
