Brick wall seperating car park from pavement falling apart and starting to lean

The brick wall separating residential parking on torridge road from Ellen road is staring to fall apart. In one section about a meter long, you can see daylight between the bricks where the mortar has fallen out but the bricks are still in place. The wall has started to lean and bricks from opposite corners have started to fall off. There are a lot of families with young children in the area who play together and they have started playing with bricks and throwing them around. This needs to be tidied up and repaired as soon as possible to prevent kids from hurting themselves or the wall tumbling onto someone walking along the pavement beside it
