A mechanic arrested during Australia's largest counter-terrorism operation was given a two-year good behaviour bond after police found a stun gun and four rounds of ammunition at his Merrylands home.

Ahmad Azaddin Rahmany, 24, was one of two men charged after more than 800 police carried out a series of pre-dawn raids across Sydney last Thursday.

Speaking to Fairfax Media last Friday, Rahmany said he was targeted because of people he had met through his business.
