New Trade Me probe

Online auction site Trade Me is investigating a second user selling chemicals that could potentially be used to make a bomb.

The site on Saturday cancelled the account of a Wellington student who had been selling the chemicals ammonium perchlorate and potassium perchlorate as fertilisers.

The quantities on sale were too small for agricultural use and the chemicals could be used to manufacture explosives, experts said. But while the site has clamped down on the 65 listings which initially raised eyebrows, a second user selling similar items still has an active account.

Staff would investigate, said Chris Budge, the Trade Me safety manager.
