The Supreme Court on Tuesday questioned the Enforcement Directorate (ED) over the "delay" in its probe into the excise policy-linked money laundering case involving Delhi Chief Minister Arvind Kejriwal, and asked the agency to produce case files before the arrest of the AAP leader.

A bench of Justices Sanjiv Khanna and Dipankar Datta also asked the ED to produce case files before and after the arrest of Delhi's former deputy chief minister Manish Sisodia, who is also an accused in the case.
