Two people have been identified as suspects by authorities investigating a deadly fire at an Indonesian lighter factory that killed 30 people including several children, a police chief said Saturday. A man and a woman, named only as the owner and supervisor of the workshop, were arrested in North Sumatra's capital Medan shortly after the fire ripped through a rented home that operated as a lighter factory in the town of Binjai, about 70 kilometres (44 miles) west of the capital.
