A GRAMMAR school has issued a warning to parents after 200 pupils across 30 schools were allegedly contacted by a man on Snapchat.
It has been claimed that a man made approaches to the pupils under the username "pastpapersolutions" on the social media platform.
Glenlola Collegiate, an all-girls grammar school in Bangor, issued a statement urging people to be "extremely cautious online".
It said: "The PSNI has been in contact with the school to inform us that a man has been in communication with approximately 200 pupils from 30 schools via Snapchat using the name 'pastpapersolutions'."
The school said they "feel it is important to remind everyone that they must be extremely cautious online when using social networking sites".
"Our advice is that if your daughter has been in contact with this individual they should block this immediately," it added.
"Further advice and guidance is available from the school internet policy available on the school website."
The PSNI told the Belfast Telegraph: "A man who had been given a Sexual Offences Prevention Order breached the order by contacting school pupils on Snapchat.
"The man was arrested and charged and appeared at Belfast Magistrates Court on December 6 and remanded. Police made schools aware and are sending out letters to parents."
