Heavy security was deployed outside AAP office in Delhi after Rouse Avenue Court on Monday sent former Delhi deputy chief minister and AAP leader Manish Sisodia to judicial custody till March 20 in Delhi excise policy case. Sisodia was produced before special judge M K Nagpal on the expiry of his seven-day CBI custodial interrogation allowed by the court earlier. The CBI last week arrested Sisodia in connection with alleged corruption in the formulation and implementation of the now-scrapped liquor policy for 2021-22.
