The federal prosecutor’s office reported that the 31-year-old man, who is identified only as Hassan Rejan B. in line with German privacy rules, was arrested on Wednesday in the Pinneberg area, near Hamburg.

He is suspected of 15 counts of supporting IS and 11 of violating German export laws.

Prosecutors report that the man made a total of 11 transfers in 2016 and 2017 to an IS fighter in Syria. They say that, in 2015, he also transferred money to a man from North Macedonia who wanted to join the Islamic State in Syria. In all, they say he transferred about 15,000 euros ($17,000), in most cases as a go-between.
