They said the Delhi-based businessman's premises were searched by the tax authorities a few days back on suspicion of "huge" tax evasion by him and his business enterprises.
"The man, who is one of the largest suppliers of medicines to the CGHS, has surrendered Rs 200 crore as black money. Tax evasion investigations against him are still ongoing," a senior Income Tax officer said.
Sources claimed that the businessman, who could not be contacted by PTI for comments, was also constructing a large mall in the national capital, apart from funding a few other large business projects.
They added that the tax department is in the process of opening his bank lockers and examining his financial documents to ascertain the exact amount of tax he evaded.
The CGHS hospitals are run by the Ministry of Health and Family Welfare, and the official website says they provide "cheap medical care to central government employees, pensioners and all the four pillars of democratic set up in India namely Legislature, Judiciary, Executive and the Press."
