A 24-year-old electronics engineer and her jobless husband were arrested on Monday for allegedly stealing her aunt’s credit card and going on a shopping spree.
Items worth about Rs 25,000 were found in the possession of Barnika Roy and Raju Das.
The goods were bought within a span of two hours on December 13. Among them was a gold ring that Barnika — whose father is a doctor — had gifted to Raju, a cellphone and a gold bracelet.
Kalpana Das, 50, whose sister is Barnika’s mother, noticed that her credit card was missing on December 12.
“The card had been issued to her by a private bank last month. On December 13, Kalpana received a call from the bank informing her that the card was being used to make random purchases. She smelt a rat and immediately informed us,” said an officer of Maniktala police station.
The bank told the investigators that the purchases were made at an electronics store in Ultadanga and a mall in Baguiati. The employees of the shop provided a description of the couple who had purchased the cellphone.
The police, however, could not obtain pictures of the duo as the closed-circuit television cameras in the Baguiati mall, where they had purchased gold ornaments worth around Rs 19,000, were out of order on December 13.
“We strongly felt that it was an insider job. Kalpana taught geography in a school in Gouribari Lane and lived alone in Maniktala. Apart from some colleagues, only her relatives used to visit her. We first found out who had visited Kalpana recently. Our first suspect was her nephew, who used to stay over at her place occasionally. We zeroed in on Barnika by the process of elimination. She confessed to stealing the card and using it during interrogation,” said Partho Mitra, the officer investigating the case.
Barnika, who graduated from a private engineering college in Garia, had married Raju, a resident of New Barrackpore, a few years ago without informing her parents.
After a stint with a mobile service provider, Barnika had worked for a private bank, which she quit recently. She lived with parents in Salt Lake.
“She told us that she stole the credit card from her aunt’s house on December 12,” added the investigator.
