The Union Home ministry has ordered a Central Bureau of Investigation (CBI) inquiry into the supply of substandard medicines in Delhi government hospitals and whether the drugs were also distributed through mohalla clinics, sources said on Friday.

The CBI probe was ordered following a recommendation by Delhi Lt Governor V K Saxena on the matter in December last year. Saxena said the drugs allegedly “failed quality standard tests” and had the “potential of endangering lives” in hospitals run by Delhi government. The Delhi government’s Directorate of Vigilance had written to the home ministry requesting the probe. “It also needs to be investigated whether the same drugs which have been procured by the Central Procurement Agency (CPA) are also being distributed to the patients through the ‘Mohalla Clinics’ or not,” the communication read.
