10 hurt when land mine explodes on Vietnam street

State media and a witness say 10 people were injured in downtown Hanoi when homemade land mines exploded on one of the capital\'s busiest streets after a botched heist at a gold shop. An employee at Hoang Tin gold shop says a man entered Thursday wearing a helmet and mask, and carrying two black plastic bags. The employee says the masked man handed staff a note saying he would detonate a land mine if he didn\'t receive gold. He says one of the shop staff threw the bags into the street, causing the explosion. The employee spoke on condition of anonymity because he was not authorized to speak to reporters. The Laborer Newspaper said in a report that a suspect has been arrested. Vietnam prohibits citizens from owning weapons.
