Several JFS pupils will not be allowed to sit their GCSE exams at the school following their involvement in the "loutish and dangerous behaviour" that caused 300 teenagers to be sent home.

It is understood that an unknown number of students have been told to make arrangements to take their exams at an alternative venue.

The measure is part of the school's response following events at the JFS muck-up day earlier this month when school property was damaged and the headteacher, Jonathan Miller, was abused.

The entire Year 11 - 300 pupils - were sent home as a result, and Mr Miller promised that a "sizeable" number of students would be dealt with "in the strongest way possible".

He added that all those involved would be facing consequences.

It is believed that JFS has now begun to inform students what disciplinary action they will be facing.

Full details have yet to emerge but it is thought that the school will decide on appropriate punishments on a case-by-case basis.

A spokesperson for the school said this week: "It would be inappropriate to provide details of the discussions that have taken place with individual families."
