I guess it all depends on what the role of Is is. From the Jakarta Post, with thanks to Twostellas:
National Police Headquarters has named a senior police officer as a suspect for his alleged role in last December’s church bombings here.
Adj. Comr. Is, who serves with the Central Sulawesi Police, was named a suspect after a police investigation into his activities since January, said Central Sulawesi Police chief Brig. Gen. Aryanto Sutadi.
Adj. Comr. Is is the first senior police officer to be named a suspect in sectarian bombings in Central Sulawesi. Other police officers linked with bombings in the province have been low-ranking officers….
“The police officer is now being detained for questioning at National Police Headquarters in Jakarta. His wife was also arrested and is being questioned at Central Sulawesi Police Headquarters,” Aryanto said.
Last December, hundreds of people in a church in Palu were praying when unknown assailants sprayed bullets into the congregation. Later that night, a bomb went off in another church in the city — Immanuel Church — injuring at least five people….
Palu is only a few hundred kilometers from the restive regency of Poso, where major bloody conflict took place in 2000. The sectarian conflict left some 2,000 Muslims and Christians dead and dozens of others fled the area for safety.
