Burmese officials say arrest warrants have been issued for about 100 customs officials charged with corruption.
Authorities issued the warrants last week after questioning all 500 Customs Department officials over the past few months.
Several officials have been sentenced to jail terms of up to 66 years for their alleged crimes.
Corruption is rampant in the impoverished military-ruled country, where low-paid officials often supplement their incomes with corrupt activities.
