Foyle MLA Gary Middleton has said action must be taken against those involved in firing shots in Londonderry during an event marking the 40th anniversary of the death of hunger striker Patsy O'Hara.
The DUP MLA said, "Over recent weeks we have seen strident police action against people involved in protests across Northern Ireland. None of those incidents involved firearms yet the PSNI has spared no efforts in pursing those involved.
Whilst the PSNI have said they are investigating last night's incident, many people will be watching to see how rigorously this is pursued. There can be absolutely no justification for bringing firearms onto the streets in a blatant terrorist display.
It is incumbent upon all political representatives in the city to condemn this incident. Unfortunately there are some parties and representatives who continue to glorify and celebrate terrorism. That sends out a dangerous signal to those who wish to replicate those tactics today."
