Last year, Jalgaon police had sought government permission to prosecute Deokar in the case and had even arrested him in May 2012 for his alleged involvement in the 15-year old mass housing scam.
However, he was granted bail by a local court, but the Bombay High Court had later cancelled it.
Deokar, a co-accused along with former housing minister Suresh Jain in the case, had subsequently moved the Supreme Court to evade arrest but the apex court earlier this month directed him to surrender in connection with the scam.
Deokar, NCP's face in Jalgaon in north Maharashtra, faces charges of criminal conspiracy, cheating, forgery and corruption in the scam involving fraud in the construction of 11,000 low cost houses.
