State education and information committee chairman Aznan Tamin said they are SK Kampung Maju Jaya and two private institutions – Sekolah Rendah Islam Hidayah and Sekolah Menengah Islam Hidayah.

He said SK Kampung Maju Jaya has 974 pupils and 64 teachers, while Sekolah Rendah Islam Hidayah has 1,232 pupils and 92 teachers, and Sekolah Menengah Islam Hidayah has 807 students and 75 teachers.

“Home-based teaching and learning will only be for today, and any extension will depend on the situation and latest reports,” he said.

SK Kampung Maju Jaya was ordered to close yesterday after 27 pupils experienced dizziness and vomiting, believed to be because of the odour pollution affecting Kampung Maju Jaya and Kampung Tawakal.

The pupils received treatment at the school from healthcare personnel and only one was referred to Sultanah Aminah Hospital for further treatment.

Johor menteri besar Onn Hafiz Ghazi has reportedly urged the police and relevant agencies to conduct a thorough investigation into the matter.
