Önnevall met the 15 year old while filming a documentary in Greece in 2014 and brought him to Sweden after the boy asked for help.
Charges were pressed against the tv-team, which also includes a cameraman and a interpreter, after the documentary aired in 2015.
According to the prosecutor the three intentionally helped a foreigner travel through Europe and enter Sweden despite the fact that the person was missing permission required to enter the countries.
– I regret nothing, Önnevall said earlier.
The Syrian boy now lives in Sweden together with his family.
