JD.com Chief Executive Liu Qiangdong was flown back to China shortly after being arrested in Minnesota on suspicion of rape, raising questions about why he was released so quickly.

According to a Bloomberg report quoted by Sina News, the criminal defense lawyer said that the reason why he was able to leave the United States smoothly showed that the case may not be what it seems.

Liu Qiangdong was released about 16 hours after his arrest last Friday.The reason for his detention was initially disclosed only as criminal sex.Police later released a report stating that the alleged crime was a criminal sexual act - rape - completed.

Afterwards, Liu Qiangdong was released abruptly without travel restrictions, and was flown home.Minneapolis Police Department spokesman John Elder (John Elder) said that although China does not have an extradition treaty with the United States, the investigation is still in its early stages, and the police are confident that they can contact Liu Qiangdong again if necessary.

Under Minnesota law, police can detain a suspect for 36 hours without charging charges, not counting Sundays and holidays.According to Manhattan criminal defense attorney Gerald Lefcourt (Gerald Lefcourt), even if police believe there is a reasonable basis for arresting someone, prosecutors may decide that there is not enough evidence to bring a charge.That is, they did not believe there was enough evidence to prevail beyond a reasonable doubt.

Apparently, something happened after this arrest -- possibly something said by the arrestee, or maybe something said by the complainant -- that made the prosecutors think it wasn't a case at all.Lovecourt said.This is not common and something must have happened after the arrest.

A series of articles published this summer by the Star Tribune covered the Minneapolis police.The special report, called Negative Justice, focuses on the way sexual assault cases are investigated.The paper's review of more than 1,000 cases filed over a two-year period found that in a quarter of them no investigators were assigned to the police; in a third of cases, victims were never interviewed; in half of the cases, not a single potential witness was interviewed.Fewer than one in 10 cases end up with a conviction for the suspect, the newspaper said.
