In 1990, the police arrested Bock and 33 other participants in the dig on suspicion of the use and distribution of indian hemp. When the court sentenced three of Bock's foreign companions the results were a public scandal and the withdrawal of the sponsor of the excavation, the major construction and roadworks company Lemminkäinen Group. Since then, smaller digs have been made. In 1999, a knife-stabbing left Bock quadriplegic. When Bock was still in hospital, his debts to the Lemminkäinen Group and to a geotechnical contractor (from 1992) were used to instigate a process against him for debts and credits. During Bock's stay in Goa the following winter, his assets were confiscated and his properties sold.
