Aam Aadmi Party leader Manish Sisodia has been arrested by another central agency a day before his bail hearing in the Delhi liquor policy case comes up in a special court, sources said. The Enforcement Directorate, or ED, arrested the Delhi Deputy Chief Minister after questioning him for two days over alleged money laundering while framing the new liquor policy, which was scrapped after Delhi Lieutenant Governor VK Saxena ordered the Central Bureau of Investigation, or CBI, to take a look.
