Sathyanarayana, an employee of a jewellery store in Andhra Pradesh, was detained by security personnel at the Central Railway Station after it was found that he had hidden the gold in his belt.
"When he walked through the metal detector, signals indicating the metal's presence was shown," an official said.
He was scheduled to take a train to Andhra Pradesh. As he did not produce valid documents for carrying the gold, it was seized.
The seizure comes against the backdrop of several incidents of thwarted attempts to smuggle gold through air to the city.
