Lawyer Kitty Kumaramangalam, the wife of former Union minister P Rangarajan Kumaramangalam, was murdered in her home in Delhi on Tuesday night, said the police. She was 67.

Ingit Pratap Singh, the deputy commissioner of police (South West), told ANI that one person had been arrested while the search for two others was underway.

The arrested person, a 24-year-old washerman named Raju Lakhhan, and his associates came to Kitty Kumaramangalam’s house in South West Delhi’s Vasant Vihar at 9 pm on Tuesday, Singh said. The man had been working for Kumaramangalam for the last five years.

Singh added that when the domestic worker at Kumaramangalam’s home opened the door, the man overpowered her, dragged her to a room and tied her up.

“In the meantime, two other boys entered and overpowered Kitty Kumaramangalam,” Singh was quoted as saying by ANI. “They smothered her using a pillow.” They stole money and jewellery from the house, according to The Indian Express.

Manju, the domestic worker, told the police that she untied her hands and called the neighbours for help. They informed the police about the incident.

The police have formed multiple teams to arrest the accused, Singh told the newspaper. “We have informed her [Kumaramangalam’s] son in Bengaluru,” he added.

Kitty Kumaramangalam had served as a lawyer at the Supreme Court. Her husband P Rangarajan Kumaramangalam, who died in 2000, held Parliamentary Affairs and Power portfolios during his career.
