Singh who is charge of AAP's Gujarat affairs surrendered before the Surat police on Sunday after a non-bailable warrant was issued against him.
The arrest comes while party chief Arvind Kejriwal is in Surat to address a rally. He was later questioned by officials of the Delhi Police, who are in Gujarat, and subsequently arrested.
Singh, the party in-charge in Gujarat, was held by the team of Delhi police days after non-bailable warrant was issued against him in extortion case. The FIR stated that two property dealers, Deepak Sharma and Rinku Diwan, had alleged that Satish and Divender, who work in Singh's office, and an associate, Jagdish, were extorting money from them. "So I am going to Umra police station to court arrest and ask the Delhi police to pick me from there".
Ahead of the MLA's arrest, Kejriwal, on his third and last day of Gujarat tour, accused BJP national president Amit Shah of going out of way to disrupt the AAP's rally.
