The Enforcement Directorate (ED) arrested former Delhi deputy chief minister Manish Sisodia in the liquor policy case, after hours of questioning at Tihar Jail on Thursday.

The ED began questioning the senior Aam Aadmi Party (AAP) leader and one of the party's founding members, days after it recorded his statement on Tuesday.

Sisodia was arrested by the CBI in the liquor policy case on February 26 and was sent to 14-day judicial custody on March 6.

The ED also made another arrest in the case earlier, as it took Hyderabad-based businessman Arun Ramchandra Pillai into its custody.

The ED, on Thursday, summoned Bharatiya Rashtriya Samiti (BRS) MLC and Telangana Chief Minister K Chandrashekhar Rao's daughter K Kavitha for questioning in the liquor policy case.

Sisodia was arrested by the CBI earlier in its ongoing investigation of a case related to alleged irregularities in the framing and implementation of the excise policy of the National Capital Territory of Delhi (GNCTD). Delhi's Rouse Avenue Court sent him to Judicial Custody till March 20.

ED, last year, filed its first chargesheet in the case. The agency said it has, so far, undertaken nearly 200 search operations in this case after an FIR was filed, taking cognisance of the CBI case registered on the recommendation of Delhi's Lieutenant Governor VK Saxena.
