"The accused was produced before Judicial Magistrate First Class, Mapusa, who remanded him in seven days police custody," police inspector Rajesh Kumar told Press Trust of India.
Mr Singh, originally a native of Bhatinda in Punjab, became the main suspect after he withdrew cash from an ATM machine in Porvorim, just 5 km from the scene of the crime, on the morning of October 6.
The perfume specialist was found murdered in her flat near here, following which the Goa police had tracked down the alleged killer and arrested him from a hotel in Bengaluru. Ms Ghurde was found strangulated to death in her three-bedroom rented apartment in Sangolda village near Panaji.
Her body was recovered on October 6, but investigation revealed she was killed a day earlier.
Rajkumar Singh had stolen two ATM cards of Ms Ghurde besides her mobile phone, and transactions made through them helped the police to track him.
The fashion designer-turned-perfumer had been living alone in the flat since July last.
Ms Ghurde had done her photography course from Mumbai's JJ Institute of Applied Arts. She moved to Chennai in 2009 to pursue her interest in perfumes, and shifted to Goa in 2011. She had set up a perfume-making company, Mo Lab.
