UPDATE: from CPJ statement 8 November 2018
"Quintal and Mumo were detained yesterday at their hotel in Dar es Salaam by immigration and security officials, taken to an unknown location, and interrogated about their work. They were allowed back to their hotel after several hours of questioning. Their passports were seized and only returned midday today. During their detention, Quintal and Mumo's phones and computers were also seized. While they were detained, a false tweet saying they had been released was sent from Quintal's personal Twitter account and repeated attempts were made to access Quintal's email. The two CPJ staff members have now safely left Tanzania."
WAN-IFRA calls on the authorities in Tanzania to immediately release Angela Quintal, Africa programme coordinator at the Committee to Protect Journalists, and Muthoki Mumo, CPJ's sub-Saharan Africa representative, after Tanzanian immigration authorities detained the pair and confiscated their passports in Dar es Salaam.
