Controversial historian Kurt William Treptow, although the order banning him from leaving Iasi city on a 30-day period has expired, was also banned from leaving Romania until the finalisation of investigations into his case, with border police having been informed on the matter. Treptow, who was initially accused of white slavery, underage children included, is currently investigated over possession of obscene materials and he is also likely to be charged with corruption of minors. As for the veil of secrecy around investigations into the case, the Prosecutor General's Office in a communiqué released on Thursday said it was required in order to protect the alleged victims in the scandal. Investigations are carried on both in Iasi and in Bucharest, with new witnesses being questioned in connection with the charges pressed against Treptow, but conclusive results are expected after the examination at the Criminalistic Institute of all materials seized from Treptow's foundation in Iasi city. Police head Florin Sandu said the first results are to be submitted to prosecutors in ten days' time. Prosecutor George Balan on Monday was assigned as chief prosecutor at the Bucharest Court of Appeal. Balan was also chief prosecutor at the Prosecutor's Office under Bucharest 2st district's court, where his subordinates included Victor Ponta, currently head of the premier's watchdog body, and late Cristian Panait, the prosecutor who committed suicide during the scandal around the arrest of controversial businessman Adrian Tarau over oil smuggling. Balan was also the head of the second department under the Prosecutor General's Office. Two Romanian citizens arrested in France over forcing children to beg are to be investigated by rogatory commissions, General Pavel Abraham, state secretary with the interior Ministry, said on Monday.
