The racket, first uncovered last month in the booming IT city of Gurgaon outside New Delhi, was one of the largest transplant rings reported in India for years and led to calls for the government to stop a booming trade in backstreet operations.
Indian media said he aroused suspicions of a hotel employee when he cut out a news article about the kidney racket from a newspaper.
"He did not resist being arrested," Gautam said.
At least five foreigners -- two U.S. and three Greek citizens -- were found last month in a luxury guesthouse in Gurgaon which was part of the racket, police said.
Suspicious neighbours said they had noticed blood running out of the house's gutters, as well as blood-soaked bandages and even bits of flesh thrown into an open plot near the house in Gurgaon, according to Indian media.
"I am innocent," he told reporters.
But police officer Upendra Kant Aryal said he could be charged in Nepal for illegally carrying large amounts of dollars, euros and Indian rupees, a charge that could fetch up to four years in jail.
