DAR ES SALAAM, Sept. 25 (Xinhua) -- Tanzania's anti-graft watchdog on Friday announced the arrest of seven top mineral dealers for their allegedly attempt to bribe senior government officials to facilitate smuggling of Tanzanite, a rare gem.
John Mbungo, the director general of the Prevention and Combating of Corruption Bureau (PCCB), said the seven mineral dealers had on separate occasions used money to bribe government official at minerals trading centers in the northern regions of Arusha and Manyara to undervalue the gemstones and evade tax.
