Along with Party Leader David Ford, the MLA for East Antrim has already requested the Assembly be recalled and has demanded answers from his Unionist colleagues.
The police have informed Mr Dickson that along with the attack on his office, the West Street area of the town has witnessed hand-to-hand combat and baton rounds have been fired. It is the second night in a row the office in the centre of Carrick has been targeted, with graffiti sprayed across the building on Tuesday night.
Stewart Dickson MLA said: “This is an outright attack on Democracy and cannot be allowed to continue. The police have informed me my office is on fire and all I can do is wait to see the extent of the damage.
“This campaign of intimidation against the Alliance Party cannot be allowed to continue. The blame lies firmly with the two Unionist parties who distributed bogus leaflets across loyalist areas in Belfast ahead of the December meeting of Belfast City Council. They cannot expect to whip up Unionist tensions and encourage people to protest and then wipe their hands of any involvement.
“The DUP and UUP have also failed to convincingly condemn both the violence that occurred in Belfast on Monday night and the threats and attacks against the Alliance Party. Any condemnation now can only be seen as hypocritical. They must be held accountable for their actions and it is for this reason that David Ford MLA and I have already contacted the speaker of the Assembly to request the Assembly is recalled this week.
“The Alliance Party will not continue to be bullied and intimidated by Unionists.”
