Senator Antonio Trillanes IV underwent booking procedures at the Makati police headquarters after he was taken into custody on Tuesday.
Police officers took mugshots of Trillanes, who was still wearing a suit he had been wearing at the Senate before he went with the arresting officers.
Makati Regional Trial Court Branch 150 earlier Tuesday granted the Department of Justice's motion to issue an arrest warrant against Trillanes. It also issued a hold departure order against the senator.
Trillanes, one of President Rodrigo Duterte's fiercest critics, said he will be posting a P200,000 bail set by the court.
Branch 150 handles the rebellion case against Trillanes and his comrades over the 2007 Manila Peninsula siege. The case was supposedly dismissed when he was granted amnesty in 2011.
Duterte had voided the amnesty granted by the past administration to Trillanes for his alleged failure to file an application form and admit guilt for two failed uprisings in 2003 and 2007.
Trillanes has insisted that his amnesty was valid and that he followed procedure, and sought help from the Supreme Court. However, the high court junked his petition.
He is the second opposition senator to be taken into custody under the Duterte administration. Senator Leila de Lima was taken arrested in 2017 on drug-dealing charges, an accusation she has repeatedly denied.
