New Delhi: A plumber and his three accomplices were arrested on Friday, a day after they had robbed and murdered two elderly sisters in West Delhi’s Paschim Vihar. Raids are underway to nab the other three conspirators involved in the case, said an officer.

The conspirators behind the double murder were identified as Raju Yadav, 34, Akhilesh Yadav, 24, Deepak Soni, 22, and Salman Shah, 19. All these accused work as labourers and are residents of west Delhi.

Police arrested Akhilesh Yadav, Deepak Soni, Salman Shah, and Raju Yadav on Friday. “The case was cracked in less than a day. The absconding trio will also be arrested soon,” said Seju Kuruvilla, DCP (Outer).

The victims in the case were Asha and Usha. Being avid readers, the two sisters went to a bookstore last week. Since they frequently visit the store, they asked the bookstore owner to recommend a plumber to fix a problem at their home.

The main accused, Akhilesh Yadav, learned about the requirement of a plumber by talking to the store owner on Tuesday. Later, he went to the women’s house posing as a plumber and stayed there for almost three hours. After familiarising himself with the layout, Yadav left promising to fix the problem the next day.

However, on Thursday, Akhilesh went to the sisters’ house with six other friends. Fearing that the women would raise an alarm, Akhilesh strangulated one woman while stabbing the other, he told the police.

According to a Times of India report, the news reached the police at around 3 pm after the domestic help visited their home. The house was also discovered to be ransacked. While the body of Asha was discovered in the living room, Usha’s body was found near the kitchen.

Usha Pathak, 70, was a retired music teacher from a college in Uttar Pradesh’s Hapur. Asha Pathak, 75, was a retired librarian from Krishi Bhawan in Delhi. Both of them were unmarried and were staying in their second floor flat for the last 30 years, stated a police officer.
