There was no damage to AAP property or any human casualty, according to Acharya.
Acharya said that the immediate provocation for the attack could be AAP's ongoing campaign against senior NCP leader and state Deputy Chief Minister Ajit Pawar highlighting alleged corrupt activities in the power department handled by him.
"We are going to 'retaliate' in a peaceful manner this evening by sweeping the NCP Andheri west office with our brooms and praying to the Almighty to give them good sense not to indulge in such violence," he said.
