The Supreme Court today told Delhi Deputy Chief Minister Manish Sisodia to go to the high court if he wants to challenge his arrest by the CBI in the Delhi liquor policy case. Mr Sisodia's lawyer Abhishek Singhvi said his arrest was illegal as his name was not in the CBI chargesheet and no unaccounted cash was found in searches. The CBI's allegation that he was not cooperating in the investigation was a weak excuse, said Mr Sisodia's lawyer.
