Police Captain Moe Yan Naing, a prosecution witness, gave details to the court of the hours leading up to the December 12 arrest of Wa Lone, 32, and Reuters colleague Kyaw Soe Oo, 28, who had accompanied him to the meeting, and said the police had arranged a "set up".

The court in Yangon has been holding hearings since January to decide whether the pair will be charged under the colonial-era Official Secrets Act, which carries a maximum penalty of 14 years in prison.

They had been working on a Reuters investigation into the killing of 10 Rohingya Muslim men and boys in a village in western Myanmar's Rakhine state, during an army crackdown that United Nations agencies say has sent nearly 700,000 people fleeing to Bangladesh.

Seven soldiers have been sentenced to "10 years in prison with hard labour in a remote area" for participating in the massacre, the army said earlier this month.

Reuters was unable to immediately obtain a comment from lead prosecutor Kyaw Min Aung as the proceedings were ongoing.

In his testimony, the police captain said he had been interviewed in November by Wa Lone about police operations in Rakhine state.

He was one of two officers from the paramilitary 8th Security Police Battalion who the police identified in December as "allegedly involved in the case".

Moe Yan Naing said he had been under arrest since the night of December 12 and had been told to testify as a prosecution witness.

He said that earlier on the day the Reuters reporters were arrested he was picked up from his post in Yangon and taken to Battalion 8's headquarters on the northern edges of the city.

When he arrived, he said he found himself among a group of several other Battalion 8 policemen who had given interviews to Wa Lone.

They were interrogated by a police "information team" about their interactions with the Reuters reporter, he said.

Moe Yan Naing told the court that police Brigadier General Tin Ko Ko, who led the internal probe, ordered police Lance Corporal Naing Lin to arrange a meeting with Wa Lone that night and hand over "secret documents from Battalion 8".

"Police Brigadier Tin Ko Ko gave the documents to Police Lance Corporal Naing Lin and told him to give them to Wa Lone and said that when Wa Lone comes out of the restaurant, the Htaunt Kyant regional police force has to entrap him and arrest him," said Moe Yan Naing.

"Police Brigadier General Tin Ko Ko told the police members, 'if you don't get Wa Lone, you will go to jail'," said Moe Yan Naing in a raised voice.

Reuters was not immediately able to reach Tin Ko Ko for comment.

International calls for release

The reporters have told relatives they were arrested almost immediately after being handed some rolled up papers at a restaurant in northern Yangon by two policemen they had not met before, having been invited to meet the officers for dinner.

Neither policeman has given testimony so far during the court proceedings.

Previous police witnesses have said the reporters were stopped and searched at a traffic checkpoint by officers who were unaware they were journalists, and were found to be holding documents relating to security force deployments in Rakhine.

Wa Lone and Kyaw Soe Oo have been in custody since December 12.

Senior UN officials, Western nations and press freedom advocates have called for their release and diplomats from several embassies were among those attending Friday's hearing.

Following Moe Yan Naing's comments in court, Reuters released a statement calling for the journalists' immediate release, claiming that the court had finally heard the truth.

"One of the prosecution's own witnesses admitted that the police received orders to plant evidence and arrest Wa Lone and Kyaw Soe Oo on false charges," the statement said.

"This case cannot be squared with fairness or justice, and it's time to bring it to an end."
