Kumar has been brought here from Chitwan in southern Nepal by road and handed over to the Kathmandu Police, Deputy Inspector General Kiran Gautam said adding, he is being kept at the Hanumandhoka police station.

The interrogation of Kumar will be starting soon, Gautam said.

Kumar (40) was arrested from Hotel Wildlife Camp in Chitwan at 5 PM yesterday, ending a fortnight long man-hunt for the doctor who is believed to have conducted over 500 illegal operations in a decade.

Wanted by police in Haryana and some other states, Kumar was nabbed hours after he checked into the hotel, 60 kms from the Indian border town of Raxaul with an associate identified as Manish Singh.

Police seized a bank draft for Indian rupees 936,000, and Euros 145,000 and USD 18,900 in cash from him.

An Interpol Red Corner Notice was issued against the tainted doctor after the massive racket with inter-state and international ramifications came to light on January 24.

CBI Director Vijay Shankar said in Delhi that they would approach Nepalese authorities for handing him over to India.

If Kumar's involvement in a kidney racket in Nepal is proved, he will be charged in a court in the country.

Otherwise, he may be handed over to India, Gautam earlier was quoted as saying.

Nepal Police have been probing Kumar's links with kidney transplant rackets in this country.

Police officials here also said that Kumar can be tried in a Nepalese court for possessing illegal foreign currency.

Whether he has involvement in illegal kidney transplants in Nepal is yet to be ascertained, they said.

Kathmandu Senior Superintendent of Police Sarvendra Nath Khanel said the police have started investigations after the arrest and a case will also be filed against him.

Kumar, for whom the police had launched an intensified search, was identified on the basis of a sketch, DIG Gautam said.

An Indian Embassy spokesman said they will establish contact with the police and try to confirm whether the arrested man is actually Amit Kumar or not.
