Srivastava said the accused later cut the bodies into pieces using an iron rod-cutting saw, packed them into six plastic sacks and dumped them into the Gomti river using his car.

Bahadur was a retired railway employee, the police said.

According to the police, Ambesh initially misled his sisters by claiming that their parents had gone out on December 8.

When the sisters insisted on approaching the police, he switched off his phone and travelled to Jaunpur railway station and ghats in Varanasi.

On December 13, the sisters lodged a missing persons complaint for their parents and for Ambesh as well.

The accused returned home on December 15 and later confessed to the crime to his sisters.

Based on a complaint lodged by his sister Archana, police registered a case and arrested Ambesh on December 16.

Station House Officer Shri Prakash Shukla said all incriminating materials were recovered, and the accused has been sent to jail.
