A construction worker from Phnom Penh was found guilty yesterday of attempting to murder his boss and sentenced to four years in jail by Phnom Penh Municipal Court. Presiding Judge Sin Visal said yesterday that 25-year-old Men Ra had attempted to beat his manager Nouv Ratana to death on October 27 in a robbery attempt. Men Ra yesterday denied charge, saying  he had merely attempted to force his boss to pay wages that had been withheld for months.
