On Wednesday, Los Angeles County prosecutor George Gascon dropped criminal charges against Eugene Yu, CEO of the Michigan election software company Konnech.

Yu was arrested in October, and stands accused of storing data on poll workers in a China-based server, which was a breach of the company's contract with LA County.

In a statement, the district attorney's office said that it had dropped the case due to concerns regarding the "pace of the investigation" and the "potential bias in the presentation" of evidence in the case.

"Mr. Yu is an innocent man," said Gary Lincenberg, Yu's lawyer, adding that "conspiracy theorists" were using the arrest to "further their political agenda."

According to the New York Times, the sudden dismissal of the case leaves questions unanswered about Yu's activities. 

"The district attorney's office did not clarify whether the company had, in fact, stored data in China. It was also not clear whether additional criminal or civil charges could be filed against Mr. Yu or Konnech from Los Angeles County or dozens of other counties that use Konnech's election management software," the New York Times reported.

Yu and Konnech had been at the center of a lawsuit against True the Vote, alongside leaders Catherine Engelbrecht and Gregg Phillips.

The organization said at a conference over the summer that its team had located and downloaded Konnech's poll worker data from the Chinese servers, and said that it had delivered the data to the FBI.
