MANILA, Philippines — Former President Gloria Macapagal Arroyo was arrested Thursday on corruption charges related to allegations of misuse of $8.8 million in state lottery funds during her administration.
Arroyo, who is now a member of the Philippine Congress, checked herself into a government medical facility after the warrant was issued and shortly before it was served. Police officials said she was arrested while in a hospital bed. It was unclear whether she would be transferred to a jail cell later.
‘‘Congresswoman Gloria Macapagal Arroyo is now under arrest and in detention, under the custody of the Philippine National Police,’’ Senior Superintendent Joel Coronel said after the warrant was served.
Coronel said Arroyo was suffering from dehydration and hypertension. She was in the same hospital suite where she spent about eight months under detention on separate charges of rigging an election before her release in July after a judge found evidence against her to be weak.
Arroyo is under investigation in connection with a variety of corruption offenses said to have been committed during her time as president, from 2001 to 2010. Additional charges are expected to be filed in the coming months. She has maintained that she is innocent of all allegations against her.
The new charges are related to accusations that Arroyo and members of her administration repeatedly stole money from the national lottery between 2008 and 2010.
The prosecution of Arroyo is a cornerstone of the anticorruption campaign of her successor, President Benigno S. Aquino III.
Before Arroyo’s arrest on Thursday, her son, acting on her behalf, filed a certificate of candidacy to run for reelection to Congress representing the northern province of Pampanga. Though Arroyo is unpopular in most of the country, her family is from the Pampanga area and she remains well liked there.
