The police have detained three people, including two women, for questioning about Friday's arms robbery at the Ansar barracks at Nayapara Rohingya refugee camp in Teknaf, Cox's Bazar.  

Meanwhile, law enforcement agencies have increased their vigilance inside the camp and its adjacent and other areas of Hnila union by the Cox's Bazar-Teknaf highway.

One of the three, Abdul Amin, 30, an auto-rickshaw driver, was detained during a raid by law enforcers in the adjoining area of the camp, police sources said. He was found injured at his house at the time and so was taken to Cox's Bazar Sadar Hospital. 

Amin claimed to have witnessed the robbery and that the criminals had attacked him, said district Superintendent of Police Shyamol Kumar Nath. But during his interrogation, he gave contradictory information that raised suspicion. 

In a visit to the hospital yesterday noon, Amin, of Jadimura village of the union, was seen handcuffed. Two armed policemen stood guard to keep an eye on him. 

Police sources quoted Amin as saying to the police that a Rohingya named Mohammad Rafique, registered with the camp, had been involved in the loot of 11 arms from the camp's armoury on Friday. He said he had seen Rafique at the spot.

Two of the three wives of Rafique -- Humaira Begum and Minara Begum -- are the other detainees.

A team of police yesterday took them to Teknaf Police Station for interrogation.

Mohammad Ishaque, chairman of D block of Nayapara refugee camp, told The Daily Star that he himself handed them over to police. 

Sub-inspector Subir Paul of the police station confirmed the detention of the three for interrogation. 

The police, meanwhile, have set up a temporary check post at Jadimura on the highway. Law enforcers have been searching all passenger vehicles going to Teknaf and Cox's Bazar.

Ansar member and Alamgir Hossain, a witness to the looting incident, filed a case with Teknaf police, accusing 30 to 335 unidentified people of the killing of an Ansar commander and looting arms, said Abdul Majid, officer-in-charge of Teknaf police. 

Inspector Kabir Hossain was given the charge of investigating the case, the OC said.

Director General of Ansar and Village Defence Party Mizanur Rahman Khan visited the crime scene at the refugee camp yesterday evening.
