To the online radicalisation of a Perth schoolboy shot dead by police at the weekend, and WAtoday has obtained a copy of an email sent by a concerned parent in the weeks before he died.

In the letter, dated April 3, the parent expressed concerns for a student named ‘Mohammed’ who, according to her child, was using the Rossmoyne Senior High School’s prayer room to convince other students to convert to Islam.

The parent said she had seen screenshots of a ‘prayer room group chat’ between students which alarmed her, including a reference to the children watching videos of Zakir Naik, a controversial figure who has been accused of spreading Islamic extremism.

“Me and my husband are worried for [our child] and our family’s safety,” the letter read.

“As a parent I am seriously concerned why my son was targeted.

“If we can be clarified about [whether] a prayer room is legal in public school premises.”

Yesterday, Department of Education director general Lisa Rodgers told Radio 6PR that, despite the letter, the Year 11 teenager was still able to access the prayer room without active supervision.

His laptop and phone access, however, had been limited and was being monitored by the school on behalf of police.

Education Minister Tony Buti had previously tried to distance himself from the letter, saying the author had raised concerns about a boy named ‘Mohammed’, which is not the name of the slain teen – a Caucasian boy who self-converted to Islam.

It’s not clear if the boy went by different names.

The minister, school and police have all moved to reassure the community they held no concerns about other students at the school being radicalised.
