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 on 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 Laborer Newspaper said in a report that a suspect has been arrested.
