Nitro likely chemical found on man named by Peters

The Middle Eastern man labelled a terrorist by New Zealand First leader Winston Peters tested positive for residue of a chemical found in explosives and heart medication.

Sources have told the Press newspaper that claims Mr Peters made under parliamentary privilege - that the man was carrying explosives - were false.

The man claimed refugee status at Auckland Airport in September and is being held in custody.

The chemical residue is likely to be nitro-glycerine, which can be sprayed under the tongue to help in angina attacks.
