Liquor businessman Sameer Mahendru was arrested by the Enforcement Directorate (ED) today in connection with Delhi's now expelled excise policy that has triggered a massive face-off between the ruling AAP and the BJP. The arrest of Mr Mahendru, managing director of Indospirits that distributes liquor, comes a day after the Central Bureau of Investigation (CBI) arrested Vijay Nair, AAP's communications chief and a close aide of Deputy Chief Minister Manish Sisodia.
