Deputy Governor Mrs Titilayo Laoye-Tomori gave the order in Osogbo during the Education Stakeholders Meeting with representatives from five local governments.
Mrs. Laoye-Tomori said the ban became imperative to instill discipline in public secondary schools.
She decried the pupilsâ€™ poor performance during internal and external examinations, saying the results did not reflect the huge spending in educational reforms.
The deputy governor urged communities to set up committees that would monitor activities of pupils in their localities.
She said â€œdue to the unruly behaviour of some pupils, any pupil caught with cell phone, charms or dangerous objects would be expelledâ€.
