A Sydney teen charged with several terror offences allegedly had documents from al-Qaeda, as well as instructions for a homemade bomb and a guide for a stabbing attack.

Sameh Bayda, from Guildford in Sydney’s west, didn’t appear at Parramatta Local Court on Tuesday morning, a day after being charged with three counts of collecting a document likely to facilitate terrorist acts.

Court papers stated two of the items over which the 18-year-old was charged were in Arabic, while a third was in English.

In the police charge sheets it is alleged that between December 1 and January 13 Bayda “did collect a document, to wit, an image of a document in Arabic text which provides instruction on how to carry out a successful stabbing attack, connected with the preparation for a terrorist act”.

Another document Bayda allegedly possessed was an “image of a document in Arabic text that provides instruction on how to make an improvised explosive device”.

The court papers also allege that Bayda had an electronic document (a PDF), in English, “published by proscribed terrorist organisation al-Qaeda in the Arabian Peninsula, connected with the preparation for a terrorist act”.

Police said a number of items were seized from Bayda on January 13, when he was subject to a Firearm Prohibition Order.

Bayda will remain in custody until he appears in court next Tuesday, where he is expected to apply for bail.

His lawyer Fadi Abbas did not comment outside court.
