It is bad enough that a passenger should refuse to pay for the journey he had just made in Hasan Wahid's taxi.
But for that innocent driver to then be robbed and beaten is truly appalling.
This was a violent and unprovoked attack on a man who had done absolutely nothing wrong.
Mr Wahid has every right to expect he will be able to go to work and carry out his duties without coming to any harm.
There is simply no excuse for what happened to him and we should all hope that the police catch the passenger – and his two accomplices – very quickly because they are clearly dangerous.
It would be worrying enough if what happened to this driver was an isolated incident.
But we are sure there are many who will be horrified to learn that there have been three similar attacks in the same area of the city in the space of a week.
The number of attacks has led taxi firms to warn that being assaulted has become an occupational hazard for drivers.
Glenn Madden, a driver himself, points out the risks for others like him and those factors are clear for all to see.
Taxi drivers often work long shifts, late at night and on their own. The hours are unsociable but the truth is that is when they are needed.
They are only trying to make a living and should not have to put up with attacks of any kind.
We are sure taxi drivers support and look out for each other whenever possible thereby doing all they can to prevent themselves from becoming victims of attacks.
The police must take these incidents seriously and do everything possible to bring those responsible to court.
And we must all play our part too, reporting anything suspicious that we see.
At this time of year many of us will find ourselves in the position of having to call on a taxi driver.
By working, they allow us to go out and not have to worry about how we are going to get home.
They do us a great service and we should return the favour by making sure that they can work in safety.
