Officials of the Transport department turned dummy passengers over the weekend to check on radio taxis plying without permit. On Friday and Saturday, officials booked themselves Ola cabs and impounded at least 20 of them on arrival.
On making dummy bookings on Sunday, however, they were informed by the company that there were no cabs available, a senior official said.
Ban on all but six taxi companies was imposed in the wake of the rape of a 27-year-old woman by a Uber cabbie on December 5.
However, it has proven very difficult to implement it.
“All the blacklisted companies still continue with their business because their web applications have not been blocked. Some like Ola cabs are even getting more aggressive with their advertising,” a senior government official said.
Since the crackdown began on December 8, the Transport department has already impounded at least 150 taxis that were found plying on Delhi roads without the requisite permits. The department later refused to revoke the ban as all the “unlicensed” taxis were operating on All India Tourist Vehicle permits.
