The Gujarat Police on Wednesday detained for questioning former IPS officer Sanjiv Bhatt here in a case relating to falsely framing a lawyer in a criminal case in 1998.
The Gujarat CID, which took Bhatt into custody following directives from the Gujarat High Court, also detained six other people, including two former police officers.
Sources said they were all being questioned and might subsequently be arrested.
When Bhatt was serving as the Superintendent of Police in Banaskantha, in North Gujarat, he was accused of trying to frame a lawyer in a fake case under the Narcotic Drugs and Psychotropic Substances (NDPS) Act.
Bhatt was dismissed from the Indian Police Services (IPS) in 2015 for taking on the then Chief Minister Narendra Modi's administration for the 2002 Gujarat riots.
In 2011, Bhatt had filed an affidavit in the Supreme Court accusing Modi of being complicit in the 2002 riots.
