The 32-year-old teacher named in sexual abuse claims that surfaced at State school earlier this week has been taken into police custody for questioning.
Three young students are also being questioned by police.
The case centres on allegations that a 14 – year old girl had been molested by students.
Police sources said that a number of other such cases are also under investigation.
It is being claimed that, last week, another female student was locked in a classroom by the teacher, who molested her together with seven male students.
