UPDATE: Ahmed Mansour has been released from prison in Berlin, Monday two days following his detention. According to the Berlin public prosecutor's office Egypt was unable to dispel concerns about the extradition process. A foreign ministry spokesman added that Germany would not extradite anyone to any country where he or she might face the death sentence.

According to a lawyer for the Qatar-based Al Jazeera channel, leading journalist Ahmed Mansour was arrested at Berlin's Tegel airport on Saturday at the request of Egypt, adding that this is a move by Egypt to, “crackdown” on the channel. The network has called for the immediate release of the Egyptian-British broadcaster.

Previously sentenced by an Egyptian court in absentia, to 15 years in prison for allegedly torturing a lawyer in Tahrir Square in 2011 which both he and the channel deny, the arrest was made as Mansour was trying to board a Qatar Airway flight heading to Doha. Spokesman for the German Federal Police, Meik Grauer confirmed that a 52-year old man was arrested at the airport at 1320 GMT following an international arrest warrant from Egyptian authorities, and the general public prosecutor has been looking into a possible extradition to Egypt.

Following his detention, Mansour told Al Jazeera, “The airport authorities detained me based on an Interpol order at the request of the Egyptian authorities. I informed (them) that the global police organisation has rejected Egypt’s request and that I have this document from the Interpol to prove that I am not wanted in any charge... They, however, insisted on holding me in their detention centre for investigation.”

Authorities in Egypt accuse the channel of inciting violence in Egypt and being the mouthpiece of the Muslim Brotherhood. Egypt declared the Brotherhood a terrorist group in 2013.
