Sivasakthi Kumanaran Nagarajan, who faced a jail term of seven years and a fine, pleaded guilty yesterday to the theft on July 4, The Straits Times reported today.
Nagarajan and two of his compatriots identified the shop in a suburb housing estate to steal the gold bars last month.
One of his compatriots, 19-year-old Vairavan Venkatesh, had allegedly posed as a customer and ran off with the gold bars after pretending to inspect them.
Venkatesh, a full time National Serviceman, told a sales assistant in the shop that his father owned a gold smith shop back home in India.
Cases against Sastha, 29, and Venkatesh are pending.
