In response to a string of robberies against gold vendors in the capital, Daun Penh district police invited around 500 local vendors to attend a workshop on Wednesday about robbery prevention. "We have taught them about measures to protect themselves from thieves, including assessing their customers' character, reinforcing their jewellery boxes and cooperating with authorities in the event of a robbery," Yim Socheat, police chief of Daun Penh district, said. This is the first such workshop to be organised by local police.
