If you're overcharging, in time either ourselves or the transport licensing branch will be dealing with you

Chief Inspector Hogg

"A number of people had been overcharged on their routes to hotels."

Chief Inspector Hogg said the crackdown would continue.

"If you're using your taxi meter incorrectly or you're overcharging, we would suggest that you stop doing that, because in time either ourselves or the transport licensing branch will be dealing with you."

All 53 cases are being processed and prosecution is likely to follow.

Benefits widespread

The operation was welcomed by the General Consumers' Council.

Spokesperson Lillian Buchanan said: "It's better for the whole industry and consumers in general.

"We want to see taxi drivers who operate a safe, honest service.

"It's not fair that those who do so are undermined by cheats."
