Tanzanian police found about 100 hectares of cannabis in five villages along the Mgeta valley and arrested 12 suspects.[1] Morogoro regional police commander Wilbroad Mutafungwa announced the discovery on Tuesday 9 June 2020 after a special operation with other security organs that lasted a week.[1]

Mutafungwa ordered the leaders of the villages in Doma ward in Mvomero district to report to police within two days for questioning.[1] He said the nearest plantation lay about 30 kilometres from a residential area, and the ward executive officer Mapambano Mkopi said the authorities had not noticed the plantations because they were far from the villages.[1]
