The complaint has been lodged by a model and an actress in regional films, who claims to be his wife.
Bangalore Police Commissioner MN Reddi said,"she has filed a complaint in RT Nagar police station against Karthik Gowda, Sadananda Gowda's son, for allegedly raping and cheating her."
Just before the complaint was filed, the minister said that he suspected a "big conspiracy". He further added,"my life is an open book. I will not lie or cheat public. This is kind of blackmail," he said.
Denying the allegations, Karthik said,"My father is a respectable man. Why should I spoil it?"
In several interviews earlier that day, the woman told local television channels that she had met Karthik through a common friend. "How can he (Karthik) get engaged to another girl when he is already married to me? Karthik had also promised me that he would convince my parents to accept the marriage."
