The attack on the police car took place outside the office of the Alliance Party deputy leader Naomi Long in east Belfast.
She has said there "can be no justification for the vicious attacks."

My thoughts are with the police officers who were there to serve the community and have been viciously attacked while carrying out their duties.
There can be no justification for attacks on the police, elected representatives or anyone else.
If Northern Ireland is to move forward then we need a strict adherence to the rule of law and respect for the democratic process.
We need this urgently before lives are lost.
