Jemaah Islamiyah
In the following years, several members of the Jemaah Islamiyah were arrested for their suspected involvement in the bombings. In 2004, two Muslim men, Mamasao Naga (a.k.a. Zainal Paks) and Abdul Pata (a.k.a. Mohamad Amir) were arrested by Philippine armed forces in Marawi City. They were supposedly identified by Fathur Rahman Al-Ghozi, a known member of the Jemaah Islamiyah, as the ones responsible for the LRT-1 train cab bombing.
