Acting on a tip-off provided by the Nepal Medical Council (NMC), the police raided hospitals where these medical practitioners were working. They were later taken under custody by the Central Investigation Bureau, according to DIG Pushkar Karki.
Most of the doctors arrested were Chinese nationals and one of them was also from Austria, a senior police officer said.
The details are yet to be revealed as the investigation was still going on, he added.
As per the existing rules and regulations, the foreign doctors have to mandatorily take permission from the NMC before joining their work.
The doctors were arrested from 4-5 hospitals in the national capital Kathmandu.
