MANILA, Philippines (AP) — A Philippine online news site critical of President Rodrigo Duterte says its chief executive officer has been arrested again, this time over an alleged investment violation.

Rappler Inc. reported that its CEO and executive editor, Maria Ressa, was served a warrant by the police after arriving at Manila's international airport Friday and was taken to a regional trial court to post bail. Ressa's co-defendants have posted bail for the new charge.

Rappler says the charges stemmed from a complaint by the National Bureau of Investigation that accused Rappler of violating the law by allowing a foreign investor to inject funds in the online news outfit.

Ressa was arrested last month and freed on bail in a libel case.
