Bengaluru/IBNS: A Bengaluru teacher has been arrested for allegedly blackmailing and extorting money from a student's father with whom she had been having an affair.

The Central Crime Branch arrested 25-year-old Sridevi Rudagi and two others- Ganesh Kale, 38, and Sagar, 28 - on charges of extortion of Rs 4 lakh from the student's father.

They also blackmailed him with photos and videos of their encounters for another Rs. 20 lakh.

According to the police, the victim, a trader living in a western Bengaluru neighbourhood with his wife and three daughters, had enrolled his youngest, a five-year-old, in the school in 2023.

He met Rudagi during the admission process, and as per him, she kept in touch, after which they began exchanging messages and video calls on a separate SIM card and phone.

Eventually, their meetings turned personal and Rudagi then extorted Rs. 4 lakh from him.

Then, in January, she demanded Rs 15 lakh.

As the father hesitated, she visited his home on the pretext of borrowing Rs 50,000.

Later, as his business suffered setbacks, the father decided to relocate his family to Gujarat. It was then he needed the child's Transfer Certificate and found himself cornered in Rudagi's office, with Kale and Sagar also present.

The latter showed the father the private photographs and videos and then demanded Rs 20 lakh, or these would be sent to his family.

The father said he tried to reason with them and negotiated a payment of Rs 15 lakh, with an initial transfer of Rs 1.9 lakh. But the demands continued.

On March 17, Rudagi called him to remind him of the payment, which is when he decided to approach the police.

Rudagi, Sagar, and Kale were arrested and sent to judicial custody for 14 days.
