Forty-four investigators of the National Anti-Corruption Bureau of Ukraine (NABU) attended two back-to back trainings on Cross-border cooperation between law enforcement agencies on corruption and economic crime investigations, which took place on 2-3 and 4-5 February in Kyiv. A team of Council of Europe experts on mutual legal assistance, economic crime investigations and asset recovery conducted a comprehensive programme comprised of issue specific presentations, discussion on case examples, and group work. Participants were able to discuss informal and formal avenues of obtaining information and evidence from abroad, good practices with letters rogatory, and apply what they had learned on a hypothetical case study involving an international bribery and money-laundering case.
