Sandhu had on May 12 surrendered before the anti-corruption bureau court which sent him to three-day police custody.
He was today produced before the court where the magistrate sent him to judicial custody, Investigating Officer Bajrang Singh said.
Sandhu, was the Additional Principal Secretary, Urban Development and Housing in 2011 when the lease deed of a cooperative land was transferred illegally to a private firm.
Meanwhile, suspended RAS officer Onkar Mal Saini, who was deputy commissioner in JDA in 2011 and an accused in the case, also surrendered before the ACB.
The lease deed was issued by Jaipur Development Authority in 2011 but was cancelled in 2013 after objection came from the company partner Manju on single deed.
The matter was later probed by the ACB which arrested Rajasthan Administrative Service officer Nishkam Diwakar, company owner Shailendra Garg and interrogated former UDH minister Shanti Dhariwal in October last year.
