One Montego Bay high school student now requires her mother's daily protection, while another is being closely monitored as police investigate a cyberbullying network targeting students and families across several academic institutions in St James.

Three students were taken into custody for questioning on Monday following the latest incident, which involved social media posts falsely claiming a teenage girl was being sexually abused by her father.

The allegations, relatives insist, were entirely fabricated and formed part of a campaign of online harassment that has spread across multiple schools and social media platforms.
