A woman whose diamond-encrusted mangalsutra went missing from her home around two years ago spotted it on the Facebook profile of a former help whom she had suspected of having stolen it.

Based on her family’s complaint on Friday, police have arrested the help and seized the mangalsutra and some other ornaments that had been missing from the woman’s home in Beleghata.

Siddhartha Churiwal, who owns two flats on the third and fourth floors of a building on Dr Ashutosh Shastri Road in Beleghata, reported the matter to Beleghata police station on Friday.

“The complainant had brought two photographs. One was an old family photograph, which had his wife wearing the diamond-studded mangalsutra,” an officer of Beleghata police station said. “The other was a recent photograph of their former help Durga Hela who was wearing a similar-looking mangalsutra.”

Churiwal told cops that some ornaments and Rs 50,000 went missing from their fourth-floor flat between December 2018 and July 2019. They had terminated Durga, 30, because they suspected her of theft but they did not file any complaint for want of evidence, the officer said.

Durga’s husband Kamalesh, who, too, worked as the family’s help continued with his services as there was nothing to prove his complicity, the police quoted the family as saying in the complaint.

A diamond-encrusted mangalsutra, three pairs of diamond earrings, some expensive saris, some silver plates, silver accessories and Rs 50,000 had gone missing from the Churiwal residence between December 2018 and July 2019, Churiwal has said in his complaint.

Earlier this week, Churiwal’s wife spotted her help’s photograph on Facebook wearing a mangalsutra similar to her’s. The profile was in the name of “Anjali Hela”, the police said.

Cops gathered the suspect’s address from her husband Kamalesh and raided their home at Lattupara on BB Ganguly Street later on Friday in the presence of a woman constable.

Durga has apparently admitted to the crime. Cops have seized the mangalsutra and a pair of diamond earrings, an officer said.

The case became easy to crack because the help’s address was available, another officer said.
