The former chauffeur worked for Ms Ono, Lennon's widow, from 1995 to 2006. He already spent 60 days in jail in 2007 in the United States for trying to blackmail Ms Ono. "We believe (he) is guilty and the suspected thief of the objects," Carsten Pfohl of Berlin's criminal police office told reporters. The items were stolen from Ms Ono's New York home in 2006. A total of 86 items - including postcards, letters, handwritten music scores and two pairs of Lennon's trademark round glasses - were discovered at a bankrupt Berlin auction house in July.
