Attacking Modi, Ashutosh, senior AAP leader and party's candidate from Chandni Chowk tweeted, "Kejriwal's arrest in Gujarat proves that Modi is scared of him and AAP and also proves that he thinks Gujarat is his fiefdom".
"People of India will not tolerate this dictatorship. Kejriwal is on a private visit to study Gujarat's development," he tweeted.
Party leader Yogendra Yadav questioned Modi's claim of law and order in the state.
"Kejriwal was going and he had no flags or wasn't with any candidate. He was not even doing any type of campaigning for polls. Police stopped him and took him to police station.
"If this kind of behaviour is given by Gujarat to a former Chief Minister of a state, I dont know how Gujarat government is flaunting about the law and order of their state," he said.
