The Delhi Police said on Sunday former Delhi law minister Jitender Singh Tomar was "not cooperating" in the investigation in the fake degree case, saying he was "reluctant" to answer questions during interrogation.
Granted two-day extended police custody of Tomar by a court on Saturday, the cops were unable to utilise the first day as educational institutes and government offices where they intended to take him were closed being a Sunday.
A senior police officer said that when Tomar was being questioned by the investigating team, he was reluctant to answer and was "not cooperating" in the investigation.
Senior police officials said they may take the AAP MLA to some colleges in Delhi and the National Capital Region on Monday, which could reveal more details in the probe.
On Saturday, a Delhi court had extended Tomar's police custody by two days after Delhi Police claimed that documents produced by him were "fabricated" and charges under Prevention of Corruption Act might also be invoked in the case.
The police had also said that Tomar, who quit as the Law Minister of Delhi after his arrest, was required for further custodial interrogation to know about the persons who had allegedly connived with him in procurement of purported fake educational certificates.
Tomar, MLA from Trinagar, was arrested in the morning of June 9 following an investigation into a complaint by Bar Council of Delhi that he had obtained a fake law degree from the Bihar college.
An FIR was registered against Tomar on June 8 at Hauz Khas police station and he was booked for alleged offences of cheating, forgery, using forged documents as genuine, forgery with intent to cheat and criminal conspiracy.
During his earlier four-day police custody, Tomar was taken to Awadh University at Faizabad in Uttar Pradesh, from where he claims to have graduated, and then to Bishwanath Singh Institute of Legal Study College at Munger in Bihar, where he claims to have studied law.
