General V.K. Singh had participated in an ex-servicemen's rally addressed by the BJP's prime ministerial nominee, Gujarat Chief Minister Narendra Modi, Sep 15 in Rewari in Haryana.
The Congress denied the BJP's charge.
"He has not been arrested, nothing has happened, only Lt Gen Vinod Bhatia has submitted a report, and said there should be a probe by an agency like Central Bureau of Investigation (CBI). The government has not decided anything nor taken any steps," Congress leader Rashid Alvi said.
"It is not possible that if a person belongs to the opposition party or has ties with a leader who has been declared as the prime ministerial candidate, action should not be taken against him. Law will take its own course," he said.
