Police believe that it is only a matter of time before someone is seriously injured if those responsible are not caught.
The first man that the police are looking for are is 5 foot 10, of skinny build, around 16 years of age and wearing a grey hoody top and jeans.
The second man that the police are trying to track down is 5 foot 2, also of slim build and younger than the other male. He was also wearing a hoody top and jeans. The second male has a small whippet type dog on a lead.
Police believe that these two people may be responsible for other incidents that have happened in the area.
