Northumbria police have warned people of the behaviour of a certain taxi driver in Newcastle.
It comes after messages were posted on social media relating to the behaviour in the east end of Newcastle.
The posts suggested that a male taxi driver has been locking vulnerable women in his vehicle.
It's understood an upfront payment has been demanded from passengers and that they have been locked in unless they agree to pay the fare - an investigation is now underway.
There have also been reports of passengers being sick in a taxi and being locked in the vehicle until they hand over property or payment as a fine.
Both male and female passengers have reported these types of incidents and we do not believe that vulnerable women are being targeted or that a driver has ever intended to harm them.
A local taxi company has dismissed an employee in connection with the reports and a police investigation is ongoing to see if any criminal offences have been committed.
Meanwhile, a 29-year-old man has been arrested by police and his taxi licence has been suspended by the local authority. His vehicle has also been seized to avoid him driving for another company.
