SYDNEY: A Melbourne teenager alleged to have bomb-making materials pleaded guilty Monday to preparing for a terror act, reports said.

The 17-year-old told the Children’s Court he was “guilty” of one charge of engaging in an act in preparation for, or planning, a terrorist act, the Australian Broadcasting Corporation said.

Two other less serious charges against the teen, who cannot be identified, were dropped and he did not apply for bail.

Earlier this year, court documents revealed that police had seized a computer from the boy’s home when he was arrested in May.

The computer contained encrypted documents entitled “Pressure Cooker Backpack Bomb with Switch Detonator” and “Make a Bomb in the Kitchen of Your Mom,” the ABC said.

The national broadcaster said other items seized during the raid included a pressure cooker and lengths of steel pipes fitted with caps.
