Cox’s Bazar Additional Superintendent of Police Afruzul Haque Tutul said the law enforcers released the foreigners at around 4pm on Sunday to their respective organisations on getting undertakings that they would not do so in the future.
They were detained at a checkpoint on Ukhiya’s Shaheed ATM Jafar Alam Road earlier in the afternoon, the police officer said.
Various security checkpoints have been set up on the roads in and out of Ukjiya and Teknaf to prevent Rohingya refugees from moving beyond the camp area.
They had been then taken to Ukhiya Police Station for questioning regarding their attempts to enter the Rohingya refugee camps without permission, he said.
On Feb 23, the Rapid Action Battalion or RAB detained 11 foreign nationals for not carrying passports near a Rohingya camp in the same area.
Police later released them after officials of their organisation, Médecins Sans Frontières or MSF, brought their passports and other documents.
