A female juvenile was arrested by police yesterday afternoon on suspicion of assault.
The arrest follows an investigation into a video posted on social media depicting an assault on a boy.
The girl is yet to be charged and as this edition went to print remained in police custody.
In a statement the Royal Gibraltar Police said the investigation is ongoing and ask the public to refrain from posting this type of material in the public domain.
The video has been posted on numerous social media groups and personal profiles, meaning it is difficult to pinpoint the original poster, police said yesterday.
Officers are still carrying out inquiries and therefore would not be drawn on certain aspects of the case.
