The Aam Aadmi Party on Monday said that the ink attack on Delhi Chief Minister Arvind Kejriwal was a part of a "conspiracy to murder him"."It (ink attack) was part of a conspiracy to attack and hurt Kejriwal. The conspiracy to murder him cannot be ruled out," AAP leader Ashutosh told a press conference here.He also slammed Delhi Police for allegedly failing to provide enough security to Kejriwal.A young woman, Bhawna Arora, threw ink at Kejriwal on Sunday at a public function held to mark the success of odd-even traffic restriction scheme. A Delhi court on Monday remanded her in one-day police custody.Ashutosh said that Kejriwal was attacked several times in the past and Delhi Police could not get away by saying that "they were caught unawares". The AAP leader said that even during Kejriwal's visit to Muktsar in Punjab, security provided by Delhi Police was "almost negligible"."When he (Kejrwal) was returning by train, there was no Delhi Police personnel with him," Ashutosh added.
