Ms. Laszlo was carrying a camera and wearing a surgical mask in September 2015 when she kicked two migrants and then awkwardly threw out her leg toward a man later identified as Osama Abdul Mohsen, a Syrian refugee, who was holding his child.

According to an indictment released by the chief prosecutor in the county of Csongrad in southern Hungary, however, she did not make contact with Mr. Mohsen and he fell as he “wrenched himself out from the grip” of a police officer.

The evidence did not suggest that Ms. Laszlo could have caused injury, the indictment said, and there was nothing to indicate that she was motivated by “ethnic considerations” or “by the migrant status of the victims.”

Ms. Laszlo apologized but has maintained that she was used as a tool to vilify Hungary’s attitude toward migrants. She was also immediately fired by her employer, N1TV, a channel affiliated with the far right.

“We are faced with a modern European folk tale,” she told the weekly Heti Valasz after the incident. “On one side is the Nazi witch, on the other the anguished asylum seeker, who has a furnished home waiting for him in Spain and whose child is passing with Cristiano Ronaldo,” she said, referring to the welcome Mr. Mohsen received in Spain after the story spread. Ms. Laszlo also repeated unfounded accusations that Mr. Mohsen was a member of a terrorist organization.
