A doctor’s daughter who was at home with a domestic help was allegedly attacked with a bonti by her cousin and one of the relative’s friends in Haridevpur on Wednesday afternoon.

The maternal cousin, referred to by a neighbour as “Keyadi”, and her unidentified male friend allegedly attacked Shalmoli Das, 24, and forced her to share the code of the lock on their safe and took away Rs 2.5 lakh and gold ornaments. They also attacked the help when she resisted, police said.

The police said Shalmoli and the help were hit with a bonti (kitchen knife) and were bleeding profusely when the accused, whose names officers did not reveal, fled.

“The victims have been admitted to the intensive care unit of CMRI with critical head injuries. The condition of the help is more critical,” said an officer.

Only the two of them — Shalmoli and the help — were in the three-storey Diamond Park house, named Solitaire, when the woman’s cousin and the friend turned up around 1.30pm, the officer said.

Shalmoli’s younger sister, a student of Class XII, was in school. The sisters’ doctor father, Arup Das, was away, too. Their mother had died a few years ago.

“Some cash and ornaments have been stolen. But right now I am only worried about my daughter,” Arup Das said on Wednesday evening.

A neighbour said the help let in the accused woman because she was a frequent visitor. Shalmoli was upstairs when the cousin and her friend turned up.

“I heard shouts that dacoits had raided the doctor’s house. I rushed to the house and found the main door ajar. The domestic help was lying in a pool of blood. Kopai (Shalmoli’s nickname) was injured, too. She was barely able to talk. All she said was ‘mamato didi esechhilo, dakati hoye gechhe (maternal cousin had come. The house has been robbed)’. She also said a man was accompanying the cousin,” said neighbour Dipika Bose.

Another neighbour, Chaitali Nath, said: “She (Shalmoli) said Keyadi (the cousin’s nickname) had come. We went to the first-floor bedroom. It was ransacked. Shalmoli asked us to alert her father immediately,” Nath said.

The safe that contained the robbed ornaments and money were in the first-floor bedroom.

The deputy commissioner of police, south-west, Nilanjan Biswas, said they had got the name of the prime suspect from Shalmoli. The two accused were not arrested till late on Wednesday.

“We are recording statements of the victims and the witnesses. The injuries are very serious,” an officer said.

The incident happened a day after an elderly resident in Ranikuthi was tied up in his own house and robbed.
