Security alert at Alliance offices in east Belfast
Alliance Party offices in east Belfast were at the centre of a security alert late on Friday night.
Ammunition technical officers examined a suspicious object and declared it a hoax at the Newtownards Road premises.
Roads were sealed off and traffic diverted as a controlled explosion was carried out.
The premises, used by East Belfast MP Naomi Long, have been targeted several times.
In the spring of this year petrol bomb attacks were carried out on the offices.
The attacks began following a Belfast City Council vote in December 2012 restricting the flying of the Union flag at the City Hall
Alliance MLA Chris Lyttle said: "It is a serious incident for the local area. It causes serious disruption, it puts people's lives at risk, it can prevent emergency services reaching the area.
"Ultimately we need people with information to share that with the police in order for them to do their job and bring these people to justice."
Police are appealing for anyone who saw anything suspicious to contact them.
