A 24-year-old man from France was sentenced to three years in jail for aggravated burglary, aiding and abetting arson, grievous bodily harm and assaulting law enforcement officers.

A 26-year-old from the central German state of Hesse received one year and five months’ probation, and a 24-year-old also from Hesse received a suspended sentence of one year and three months.

Two further defendants from Hesse were sentenced to community service for breaching the peace.

The summit meeting of the world’s major economic powers from July 6 to 8, 2017, was overshadowed by massive riots, much of it perpetrated by far-left extremists.

In all, police said 797 officers were injured and damage was caused worth an estimated 12 million euros (13.5 million dollars).

The defendants were found to be among a group of 220 masked rioters who set numerous cars on fire and attacked patrol cars along the city’s Elbchausee thoroughfare on the morning of July 7, 2017.

Prosecutors had called for significantly harsher sentences ranging from two-and-a-half to close to five years. The defendants pleaded for acquittal.

It has taken a long time to identify suspects, with police launching repeated publicity campaigns to find unknown rioters using photos of the unrest.
