Yadav was arrested late Monday. He was the person who had introduced Rajasthan Royals cricketer Ajit Chandila to bookie Sunil Bhatia, who is already in custody, a police official said.
This takes the total number of arrests in the case to 16.
Sreesanth, Ankeet Chavan and Chandila as well as 11 bookies have been arrested for alleged spot fixing. They were Thursday sent to five days police custody by Chief Metropolitan Magistrate Lokesh Kumar Sharma.
They will be presented in court Tuesday and police is likely to seek extension of the custody, sources said.
