On Wednesday, the Taliban arrested Noor Agha Ibrahimi, an activist, in Kabul, for the third time.
He has been previously detained on charges of collaborating with the National Resistance Front.
A source close to Ibrahimi's family told Afghanistan International that they do not know his current whereabouts.
Ibrahimi was first arrested during the early days of the Taliban's return to power, but was released after some time when the Taliban could not prove his collaboration with the National Resistance Front (NRF).
However, according to Ibrahimi's relatives, he was detained again a few months ago on charges of cooperating with the NRF and spent four months in a Taliban prison.
Before the Taliban's return, Ibrahimi was active in social and political activities. His father, Waseel Ibrahimi, was an advisor to the First Vice-President in the previous government.
The Taliban have not yet commented on the detention of this activist.
According to information from the Taliban's prison administration, over 12,000 people are being detained in their prisons nationwide.
Taliban officials claim that there are no political prisoners in their jails. However, the United States recently stated that more than 90% of prisoners under the Taliban are political prisoners.
