JAKARTA, Indonesia – Security personnel arrested a dozen terror suspects across Indonesia this past week, National Police spokesman Insp. Gen. Saud Usman Nasution said Monday (May 7th).

Seven suspects were arrested in Central Jakarta on May 3rd, four in North Sumatra on May 4th, and one in South Sumatra on May 5th, Saud said, according to multiple media reports.

"We've seized firearms and other weapons, but we can't share anything more because we're still developing the cases," Saud said.

According to Metro TV News, another police spokesman, Sr. Comr. Boy Rafli Amar, revealed Tuesday that the suspects were thought to be linked to an established terror cell in Solo, Central Java where a suicide bomber attacked a Christian church in September 2011, injuring 11 people.

Terrorism expert Noor Huda Ismail said the arrests underline the latent danger of terrorism in Indonesia where militants await a mobilising figure to lead them in another large scale attack.

"Terrorist cells like this are still active. It can be seen from how easily Dulmatin hid in Indonesia for two years. If there weren't people to protect him, how could he have done it?" Gatra News quoted Noor as saying, referring to the senior Jemaah Islamiyah figure shot dead in March 2010.

"Those who can make bombs are more than a few. Those who have the ideology are more than a few. They only need a person who can bring them together," he warned.
