Kolkata: Police have arrested Abhishek Majumdar for the murder of 42-year-old homemaker Soma Ghosh, who he had befriended over the social networking site Facebook a fortnight ago.

“We have solved the case. Abhishek Majumdar, whom we have arrested from Bolpur on Wednesday evening, has admitted that he had murdered the housewife in a fit of rage and fled. Investigations have revealed that no one else was involved in the crime,” Santosh Nimbalkar, additional police commissioner, told Gulf News.

During the investigation, police questioned her husband Sujit, a family friend and a neighbour who also had a link in the Facebook chats between Ghosh and Majumdar.

“After interrogating [the neighbour], we came to know about Soma’s new friendship with Nandan aka Abhishek and started tracking him down,” an officer said.

Police inform that Majumdar befriended Ghosh on the networking site using a fake profile using the name Nandan Sen. Ghosh and Majumdar began chatting regularly and seven days later reportedly exchanged phone numbers.

Police say Ghosh invited Majumdar to her home. He went to Ghosh’s apartment complex on Monday and was escorted to her flat by a next-door neighbour.

Investigating officials have two theories about what transpired next.

“Both the man and the woman were shocked to find the real human being to be different from the virtual world. Majumdar is married and has a son. The short, slightly built man had posted the jazzy photo of a biker on his Facebook profile,” said an investigator.

“Majumdar desired a ‘closer relationship’, which Soma strongly opposed. She was the mother of a 17-year-old girl. But the youth could not take her rejection and tried to force her. There was a scuffle and she fought back. When she fell on the floor unconscious after the beating, Majumdar cut her throat and fled with Soma’s phone as he was afraid that the numerous SMSs exchanged between the two would have led police to him,” said an officer, adding that the murder was not planned.

Another theory is that he might have been blackmailing her. Since the family says some gold bangles are missing, police are investigating if Majumdar took them to make it look like a robbery.
