Accusing the AAP of playing with the sentiments of the people, Thackeray said Kejriwal had termed as "fake" the Batla House gun battle in Delhi in which three terrorists were gunned down and a policeman was martyred.
"He has also insulted our brave soldiers fighting enemies on the country's borders... This statement (by Kejriwal) is nothing short of treason for which Kejriwal must apologize," Thackeray said.
"Kejriwal and Co had spoken about travelling to work by metro rail and not occupying big government bungalows. But ... they threw to winds all their promises and assurances," he said.
