The owner of a disabled taxi has now been left with no vehicle and his passengers with no means of transport in the run up to Christmas.
It is the latest in a spate of deliberate attacks on homes and vehicles across the city recently.
Councillor Mellon said: “Attacks on anyone’s car or property is despicable under any circumstances but an added dimension to these arson attacks is that they were not only on property but the lively-hoods of the individuals affected.
“One of these taxis was also a disability access vehicle.
“I condemn these attacks on people who are providing a service to our community under very trying economic circumstances.
“To wilfully leave anyone without an income at anytime is deplorable but in the mouth of Christmas is an indication of the lack of consideration that these thugs and criminals have for anyone but themselves.
“I urge anyone who has any information on those responsible to come forward so these criminals can be brought before the courts to answer for their anti-community activities.
“These actions are an attack on our entire community and should not be tolerated.
“This area has a lot to offer to its residents and there should be no hiding place for those who are hell bent on destruction,” added Cllr Mellon.
