Jakarta, Indonesia (CNN) -- An Islamic cleric detained last week in Indonesia has been formally arrested, accused of helping fund and establish a terror cell and military training camp.
Abu Bakar Bashir's arrest allows the police to keep him in custody until December 13.
Bashir was detained August 9, when police said he played a key role in the establishment of a militant training camp in Indonesia's Aceh region.
Under Indonesia's anti-terror law, police can detain a suspect for questioning for seven days. An arrest warrant was issued Sunday, allowing authorities to extend Bashir's detention.
His lawyers refused to sign the warrant, saying they question the circumstances of his detention and arrest.
Bashir "rejects and denies all the charges against him," lawyer Achmad Michdan said.
The Muslim cleric has also refused to answer questions in his interrogations. Bashir believes his arrest was a result of pressure by the west, particularly the United States, Michdan said.
Bashir -- a religious leader known for his anti-Western rhetoric -- has been arrested twice previously for his activities in connection with militant groups. CNN
