Delhi Law Minister was detained on Tuesday in a case relating to an alleged law degree, police said. An AAP leader, however, said the minister was arrested.
"Tomar has been detained and not arrested. This is in regard to the complaint by the Bar Council of Delhi in connection to the alleged fake law degree and enrolling himself as an advocate," a police officer told IANS and added that he will be released in a few hours.
Delhi Police chief B.S. Bassi said he didn't know anything about it as he was in a meeting.
The minister was taken to the Hauz Khas Police Station.
Aam Aadmi Party leader Sanjay Singh, however, tweeted that the Delhi Police has arrested the minister without any notice or prior information.
Tomar told CNN-IBN that that he didn't know why he was arrested.
"Around 30-40 policemen asked me to accompany me to the police station without any prior notice," he said.
Tomar alleged that this was being done to tarnish the image of the Aam Aadmi Party (AAP).
Two cases are pending against Tomar in the high court, alleging that he had enrolled himself as an advocate on the basis of a "fake and bogus" graduation degree while the other plea sought cancellation of his election.
Bihar's Tilak Manjhi Bhagalpur University, from where Tomar claimed to have obtained his law degree, had earlier told the court that the provisional certificate is not "genuine" and the document "does not exist in the university's record".
The serial number of the provisional certificate in the record showed the name of another person and not that of Tomar, said the university.
