Police prosecutors have dropped a charge against a soldier who caused panic after jogging through suburban Brisbane with a gun-shaped object last year.

A full-scale police response was launched after 26-year-old Nicholas Paul Latham was spotted running through Rochedale South wearing camouflage clothing and carrying the object in December last year.

Several schools were shut down and Mr Latham was eventually tackled by police.

He told police it was all a misunderstanding as he was training with a metal object shaped like a gun, but was charged with public nuisance.

His matter went before the Holland Park Magistrates Court on Brisbane's south side this morning, where prosecutors dropped the charge.
