Five members of the Indonesian military have been arrested for alleged involvement in a people-smuggling operation.
The five soldiers were arrested on Wednesday morning in the company of 41 asylum seekers, believed to be from Iran and Syria.
It's believed the soldiers, who were in uniform, were escorting the group to a beach in southwest Java where they were set to board a boat to Australia.
The latest arrests come as another five Indonesian soldiers await trial over alleged involvement in organising an asylum seeker boat that sank on its way to Australia last year.
As many as 200 people drowned when the overloaded boat, packed with about 250 asylum seekers, sank off the coast of East Java.
Just 49 people survived the tragedy, which occurred in rough monsoonal seas on December 17.
Indonesian authorities said the asylum seekers detained on Wednesday are believed to include a number of people from Syria, which has been racked by 16 months of fighting between rebel forces and the government of President Bashar al-Assad.
Local Indonesian police said the asylum seekers were from Iran.
The Iranians, together with five men wearing Indonesian army uniforms, were arrested in the early hours as they arrived in four vans on Java island's western coast, Sukabumi district police spokesman Martinus Sitompul said.
"We arrested them at 3am (0600 AEST)," he said.
"All of them were Iranians, including 12 women and eight children.
"Five men in Indonesian army uniforms were with them and we are investigating whether they are really with the military or if they were wearing fake uniforms."
