The bribery scandal involving wealthy businessman Park Yeon-cha and which has caused political turmoil over the past six months has finally come to an end.

The Supreme Prosecutors' Office announced the result of its investigation on Friday, indicting 21 people on charges of accepting money from Park, chairman of shoemaker Taekwang Industry. Those indicted include the CEO of Sejong Namo Tour, a former head of the National Police Agency as well as two former National Assembly speakers.

Prosecutors have also decided to terminate the case of a separate corruption scandal centered around late former President Roh Moo-hyun. The decision regarding whether or not details of the investigation should be revealed has been a controversial topic. However, prosecutors say the case lost the right of arraignment after the ex-president's death.

The scandal first began last September with an investigation into the acquisition of Sejong Securities by the state-run National Agricultural Cooperative Federation. Park Yeon-cha himself and Roh Gun-pyeong, the former president's elder brother were arrested in December for offering and receiving money. In April, the investigation developed into the summoning of Roh, his wife, former first lady Kwon Yang-sook and their son Gun-ho.

The speedy probe, however, slowed down after Roh's death last month and Prosecutor General Lim Chae-jin's resignation last week amid mounting accusations blaming the prosecution for its intense interrogation which they believe led to Roh's suicide. While the results of the investigation have now been announced, some are still criticizing the investigation as being too rushed and incomplete.
