The accused -- 28-year-old Vinay Parmar, 25-year-old Tarun Harvodiya and 40-year-old Mohd Adil Sheikh -- took advantage of the non-functional CCTV cameras at the museum and carried out the theft, the police added.
Mr Sheikh was arrested yesterday from southeast Delhi while two were already arrested in Kolkata two weeks ago, the police confirmed.
On October 31, D Rama Krishna Rao, administration and security officer filed a police complaint alleging that 16 antique Pashmina shawls were stolen from the museum in the last two days when the museum was closed, they said.
The accused had already carried out a recce and found that the CCTV cameras were not functioning. Two people had been regularly visiting the museum, posing as scholars researching on antiques, the police said.
On October 22, one of them had hid himself in the museum and after over an hour later, the suspect had raised an alarm that he was stuck inside the museum, they said.
After he was rescued, he told his accomplices that the CCTV were not functional in the museum, the police said.
It was found that the mobile phones of the accused were active in Kolkata, West Bengal, they said. A police team departed for Kolkata and Mr Parmar and Mr Harvodiya were arrested on November 13. Fifteen shawls were recovered from Mr Parmar's in-laws' place in Kolkata.
Subsequently, the third accused, Mr Sheikh, was arrested yesterday from southeast Delhi's Okhla and a shawl was recovered from him, they said.
During interrogation, they disclosed that they were inspired by popular Bollywood film 'Dhoom 2' in which actor Hrithik Roshan committed theft of antique items from a museum, BK Singh, Deputy Commissioner of Police (New Delhi), said.
Mr Parmar is fluent in French and German and has visited France, Germany and China. He has a good knowledge about antiques and their importance, he said.
Mr Sheikh works as an exporter and a vendor of the Central Cotton Industries (CCI).
