Hours after the Enforcement Directorate (ED) sources claimed that senior Aam Aadmi Party (AAP) leader Sanjay Singh has links with the Delhi unit chief of Kerala-based Islamic outfit Popular Front of India (PFI), Delhi Chief Minister Arvind Kejriwal on February 6 lashed out at the ED accusing the probe agency of working as per the BJP's orders. Addressing a press conference, Kejriwal claimed that the ED is doing politics and if Sanjay Singh has committed any crime then he should be arrested.
