The Anti-Corruption Bureau of the Rajasthan Police registered the cases against four private nursing colleges in Jaipur and one in Jodhpur, IGP ACB Umesh Mishra said.
After receiving complaints, the ACB conducted raids at 76 nursing colleges and detected "irregularities" in five of them, he said.
These colleges managed to get no objection certificates from the government despite "poor infrastructure and below-standard facilities", the IGP said.
