BERLIN (AP) — German police have searched the apartments of 22 people suspected of involvement in the rioting that accompanied the Group of 20 leaders' summit in Hamburg in July.

Hamburg police chief Ralf Martin Meyer said Tuesday that they are suspected of being part of a group of anti-G-20 rioters who threw stones and other objects at police. They face an investigation into suspected breach of the peace.

Hamburg saw three nights of violence during the anti-globalization protests as leaders of the world's biggest industrial and developing countries met in the northern port city in early July.

Investigators launched the raids in various parts of Germany early Tuesday morning. News agency dpa reported that they seized computers, cellphones and USB sticks, but chief investigator Jan Hieber said there were no arrests.
