It was on Thursday that Medin was arrested when he landed at Istanbul's airport. He had traveled to Turkey to monitor the democracy protests in the country.
In connection with these demonstrations in Turkey, they have once again begun to physically attack journalists, says Erik Larsson, chairman of Reporters Without Borders Sweden.
He adds that press freedom in Turkey has been strongly threatened for several years.
Joakim Medin is accused of insulting Turkey's President Recep Tayyip Erdogan and of being a member of a terrorist organization.
This is not unique to Joakim Medin, says Ulrika Hyllert, chairman of the Journalists' Union.
Being accused of terrorism or insults is a very common method used in Turkey against opposition, journalists, human rights activists, and ordinary citizens to silence them.
She adds that the imprisonment is very serious.
This is an attack on both an individual journalist and media freedom in Turkey.
