The All India Institute of Medical Sciences  has been asked by the Delhi high court to respond to a plea for scrapping this year's entrance examination for post-graduate medical course, held last month, in the wake of reports of copying at some centres.

Justice Hima Kohli asked AIIMS to file within a week the records pertaining to the examination at all 156 centres where entrance tests were held on January 8.

The court direction came on a petition by a group of PG candidates, who alleged that incidents of cheating and copying, reported from various centres including Noida, was part of a widespread scam.

Seeking a court order for a thorough probe into the alleged scam, the students said the AIIMS, which conducts All India Post-Graduate Medical Entrance Examination, should cancel the January 8 examination and hold it afresh.
