Delhi Police yesterday arrested a man for allegedly murdering his colleague, dismembering his body and storing in a refrigerator at his home in south Delhi's Saidulajab, Mehrauli area.

The man, identified as 31-year-old Badal Mandal, murdered Vipin Joshi allegedly because he suspected him of having an affair with his wife, police said. 26-year-old Joshi's body was found on October 15 after he went missing and his family members launched a hunt.

Mandal, also known as Swapan Singra, and Joshi worked at a restaurant together. Mandal was from Rourkela in Odisha after one of his relatives informed the police.

According to police, Badal told cops that he had seen Joshi visiting his house a couple of times in his absence. He suspected his wife of having an illicit affair with Joshi, following which he planned to kill him.

He had applied for leave at his workplace before killing Joshi so that no one would suspect him of killing Joshi, a senior police officer said.

On the day of the murder, Mandal took a meat cleaver from the restaurant he worked at and drank alcohol with Joshi drank alcohol at his Mehrauli flat. Mandal then killed Joshi with the cleaver and then used the weapon to sever the dead body's head, police said.

Mandal then hid the body parts in a refrigerator and fled to his in-laws' house in Kolkata.

On the hunt for Mandal, a Delhi Police team reached Kolkata after tracking his cellphone's location to Purulia village, but he wasn't found there.

The police team then went to Tatanagar, where one of Joshi's relatives said he was in Rourkela. Badal had even procured fake identity cards and documents to throw the police off track, but he was arrested, the police said.
