Aam Aadmi Party MLA Prakash Jarwal was arrested by police on Tuesday night in connection with an alleged assault on Delhi Chief Secretary Anshu Prakash by two AAP MLAs, an AAP leader said.

"One AAP MLA Prakash Jharwal has been arrested by Delhi Police on a frivolous complaint by IAS," AAP chief Spokesperson Saurabh Bharadwaj said in a tweet.

"Delhi Police arrested elected MLA without any evidence. What about arrest of IAS officers who can be seen beating Minister in Secretariat? There is FIR by minister as well as video evidence, but no arrests," he added.

On Tuesday, the Chief Secretary alleged that he was beaten up by AAP MLA Amanatullah Khan and another party MLA, whom he can identify, in front of the Chief Minister at Kejriwal's residence on Monday midnight, where he was called for a meeting.
