Haryana Transport Minister Krishan Lal Panwar detected and seized the private bus bearing Haryana registration number, an official release said here.
The bus was plying on the Mewat-Gurgaon route, it said.
Panwar has earlier also conducted raids and seized such buses which had been painted to look like state roadways buses.
In June this year, the authorities had impounded 10 such buses which were plying on the Jaipur-Delhi route, out of which six had been painted to look like Haryana Roadways buses.
