Jakarta. National Police counterterrorism unit Densus 88 arrested two individuals on Saturday (27/05) believed to be linked to the twin suicide bombings at the Kampung Melayu bus terminal in East Jakarta last week.
The two, known only by the initials R and K, respectively, were arrested in the Cibubur neighborhood of East Jakarta.
Police say both individuals were previously suspected of having communicated with the two suicide bombers who carried out last week's attack, which killed three police officers and wounded 12 others.
The Islamic State (IS) group claimed responsibility for the bombings on social media.
National Police spokesman Insp. Gen. Setyo Wasisto said R had met with one of the bombers, Ahmad Sukri, and furnished him with an unknown item prior to the attack.
"It was a direct contact [...] R gave something to Ahmad Sukri," Setyo told reporters in Jakarta on Sunday.
Setyo added that police seized evidence from the two individuals, including two cellphones, Rp 1.8 million ($135) in cash and a wallet.
Densus 88, who is currently interrogating both individuals at the unit's headquarters in Depok, West Java, is still working to uncover what item R had given to Ahmad.
"We are continuing with our probe [...] Densus 88 has seven days to establish whether they are witnesses or suspects, and to bring formal charges," Setyo said.
On Friday, police arrested three people in Bandung suspected of being linked to the Kampung Melayu attack. Investigators seized Islamic texts, phones and other items during the raid.
According to Reuters, police said Wednesday's attack had targeted officers, using pressure cookers packed with explosives.
