WASHINGTON, United States — Prosecutors in the federal case against Sean “Diddy” Combs have dropped several significant charges, including kidnapping, attempted arson and some elements of sex trafficking.

The move comes as the prosecution concluded its arguments on Tuesday and reportedly stems from a lack of sufficient evidence, particularly in proving claims that Combs kidnapped former employee Capricorn Clark and was involved in the explosion of rapper Kid Cudi’s car.

According to Fox News, the government indicated, in a letter to the judge filed Tuesday, that the theories of attempted kidnapping, attempted arson and aiding and abetting sex trafficking will not be pursued.

“Specifically, the government has removed instructions from the charge relating to (i) attempted kidnapping under both California and New York law, (ii) attempted arson under California law, and (iii) aiding and abetting sex trafficking. The government is no longer planning to proceed on these theories of liability so instructions are no longer necessary,” the report said.

The developments come amid mounting scrutiny of the strength of the government’s case. Diddy’s legal team had already filed a motion for acquittal, arguing that the prosecution failed to present compelling evidence to support the charges.

“There’s, at best, thin proof any of the other employees participated,” attorney Alexandra Shapiro was quoted as saying in the report, “There is no evidence any of them believed he was sex trafficking.”
