"The Police Commissioner was requested to ensure that the taxis having all-India tourist permits are not seized by police personnel and passengers are not harassed," Gupta said.
Gupta led a delegation of representatives of various taxi tourist associations to the meeting.
The ban on plying of 27,000 diesel-run taxis had yesterday come into force following the Supreme Court's refusal to extend the April 30 deadline fixed for conversion of diesel-run taxis into CNG ones.
"The taxi operators are suffering for no fault of theirs. They have been issued permit and allowed to operate by the Delhi government," Gupta said.
They have taken vehicle loans and now they are fighting for survival, he said and appealed to the Delhi government to help taxi owners and extend them financial aid to get CNG kits fitted.
