The Delhi High Court on Monday granted bail to Aam Aadmi Party (AAP) MLA Amanatullah Khan in the Chief Secretary assault case.
Delhi Chief Secretary Anshu Prakash had alleged that during a meeting at Chief Minister Arvind Kejriwal's residence he was assaulted by the AAP MLAs.
The court had granted bail to other MLA Prakash Jarwal last week.
On February 20, the Chief Secretary had lodged a police complaint and alleged that he was manhandled by the two lawmakers.
Khan and Jarwal were arrested in the case on February 21.
A magisterial court had earlier denied bail to both of them, saying the matter cannot be treated in "a casual and routine manner" while dubbing them as "history-sheeters".
Jarwal had then moved a sessions court and was again denied the relief with the court saying the situation could not be more alarming when lawmakers do not respect the rule of law.
Prakash had alleged that the attack was "premeditated" and a "conspiracy" of all those who were present at a meeting there last night.
Since the party has come to power in Delhi, the bureaucracy and the AAP dispensation have clashed on a range of issues.
In December, 2015, when Delhi Home Minister Satyendar Jain suspended two special secretaries, IAS and DANICS (Delhi Andaman and Nicobar Islands Civil Service) officers went on mass leave against the move.
