People Before Profit MLA Gerry Carroll has called for an end to "reckless" attacks on Glider and Metro workers.
Mr Carroll raised the issue with Infrastructure Minister Nichola Mallon in an Assembly question, asking for an update on the action being taken to ensure Glider and Metro workers are safe from attack.
Translink services in Mr Carroll's own West Belfast constituency have been temporarily terminated on a number of occasions recently due to incidents.
