Five teenagers were sent home from the Scottish summer camp of United Synagogue youth movement Tribe for “dangerous” and bullying behaviour.
Two had set fire to objects on Shabbat using aerosol cans and lighters. The other three were said to have engaged in bullying.
The year seven tour attracted 90 12- and 13-year-olds, who visited Edinburgh for a week-long programme including physical activities and tours of the city.
A source said “the entire group was given a lecture on bullying after a group was sent home for bad and dangerous behaviour.
