A human rights group is demanding the release of activist Boniface Mwangi, who has been missing for some days now.

Through its CEO, Hussein Khalid, VOCAL Africa raised concern over the whereabouts of Mwangi and Ugandan lawyer and journalist Agatha Atuhaire, who are said to have been apprehended by Tanzanian authorities.

Khalid said both are still missing despite reports they had been deported from Tanzania on May 20.

According to Khalid, efforts to trace the two in Dar es Salaam have failed.
