As the prosecution and the police are simultaneously investigating the suspicion of preferential treatment for the Daejang-dong development project, the controversy over the overlapping investigation is rising.



On the morning of the 15th, the 4th deputy chief prosecutor Kim Tae-hoon of the Seoul Central Prosecutor's Office's investigation team seized and searched the home of Yoo Dong-gyu, the former head of the planning division of Seongnam Urban Development Corporation, who is the key figure in this suspicion, to secure a cell phone used in the past.



The acquaintance is a woman A, who is known to have remarried to former General Manager Yoo, and it is estimated that the cell phone that the prosecution secured was used by Yoo about two months ago.



This is a different phone from the one the police recently confiscated.



Previously, Police Inspector Song Byung-il of the Gyeonggi Nambu Police Agency's investigation team searched and found a cell phone that Yoo, the former general manager, tried to conceal by throwing it out of the window during the search and seizure process of the prosecution's residence on the 29th of last month.



This mobile phone is currently undergoing forensics at the Digital Forensics Center of the National Investigation Headquarters.



It is highly likely that meaningful evidence will be obtained if the prosecution newly acquires another cell phone from Director Yoo in addition to the cell phone obtained by the police.



However, in the process, a discord between the prosecution and the police has arisen, causing controversy.



The police also applied for a search and seizure warrant for Mr. A's home on the 13th while looking for Yoo's cell phone in the past.



In this situation, when the prosecution started a search and seizure, the police responded that "I was intercepted."



The timing of the request for the warrant issued by the prosecution has not yet been confirmed.



Even when it comes to investigations into Seongnam City Hall, which is the subject of licensing and approval for the Daejang-dong project, the police and prosecutors are showing different investigation behaviors.



The prosecution executed a search and seizure warrant this morning, and the police launched an arbitrary investigation on the 7th.



It is known that the two sides did not go through any special consultation process during this process.
