The wife and daughter of the former Karnataka director general of police who was found dead with multiple stab wounds at his Bengaluru home on Sunday, have been booked for murder, the Deccan Herald reported on Monday.

Om Prakash, 69, was stabbed more than 10 times in his abdomen, chest and hands, The Hindu quoted unidentified police officers as saying. Additional Commissioner of Police (West) Vikash Kumar Vikash told The Indian Express that a sharp weapon was found near Prakash’s body.

The police received information about the incident at Prakash’s home in HSR Layout at around 4.30 pm, Vikash said, adding that a complaint was filed by the son of the former director general of police.

“Based on this, an FIR will be registered and we will investigate the case accordingly,” he had said.

Prakash was with his wife Pallavi and daughter Kriti when the incident took place, The Indian Express quoted unidentified police officers saying. Both of them locked themselves in a room before the police arrived, the officers added.

The preliminary investigation suggests that Prakash had an altercation with his wife on Sunday, Deccan Herald reported. The argument escalated and resulted in his murder. The daughter, Kriti, was also at home at the time.

Karthikesh, the son of Prakash, told the police that his father had lived at an aunt’s home the previous week and that Pallavi had allegedly made death threats, Deccan Herald reported. Kriti had brought him back home on Friday, he claimed.

The wife had been detained by the police for questioning.

Vikash also noted that there were three persons at Prakash’s home when the incident happened.

“Initial investigation suggests that things might be internal in nature,” The Hindu quoted the additional commissioner of police as saying. “No arrests have been made yet…It seems some sharp weapon has been used, which led to blood loss and death,” he added.

Prakash hailed from Bihar’s Champaran district and was a 1981-batch Indian Police Service officer. He took charge as Karnataka’s director general of police in 2015 and retired in 2017.
