Staff on Belfast's Glider system have been attacked for the fourth time this week.
On Saturday, May 6, two members of staff were assaulted at a bus stop in the Lanyon Place area of Belfast. One was punched in the face, while the second was kicked to the side of the head.
This is the fourth attack in the space of a week and comes after a £1,000 reward was offered for help catching assailants following three the previous incidents.
