Amar Singh was questioned for three-and-a-half hours today by the Delhi police.

The police, however, have not ruled out the possibility of Singh being questioned again and it could take place after a status report is filed in the Supreme court next Friday. BJP MP Ashok Argal, who was allegedly sought to be bribed, is expected to be questioned on Monday.

Amar Singh's appearance before the police comes after the Delhi Police issued summons to him under Section 160 of the Criminal Procedure Code, asking him to present himself before the Crime branch.

He drove to the Crime branch's Inter-State Cell in Chanakyapuri at 10.45 amin his Mercedes car. The decision to call Singh for questioning comes after the arrest of Suhail Hindustani, who allegedly acted as a liaison between Singh and BJP MPs.
