German police were on Friday searching the foundations of a warehouse belonging to the Hells Angels for the body of a Turk who disappeared two years ago, a day after launching a massive raid operation against the gang.

Police said the disappearance of 47-year-old Tekin Bicer from the northern city of Kiel was being treated as suspicious. They believe his disappearance could be linked to a falling out with the gang over drug dealing. Police had completely emptied the warehouse on Thursday.

Around 1 200 police on Thursday carried out raids on 89 properties including brothels, hotels and apartments linked to the Hells Angels, focusing on the northern state of Schleswig-Holstein of which Kiel is the capital.

Five leading members of the chapter in Kiel were arrested, according to police. Preliminary investigations had also begun against 69 suspects. - Sapa-dpa
