Members of Armed Police Battalion (APBn) arrested a Rohingya citizen from a Kutupalong camp in Ukhia upazila of Cox’s Bazar on Friday for his suspected involvement in killing prominent Rohingya leader Mohibullah.
The arrestee was identified as Md Selim alias Lomba Selim, 27, a Rohingya refugee living in the camp.
Police registered a murder case in connection with the killing on Wednesday night.
An FIR was filed against unknown persons in this regard at the Ukhia police station on a complaint from Mohibullah's brother Habib Ullah, said officer-in-charge Sanjur Morshed.
Mohibullah was buried in Lambashia camp-1 in Ukhiya upazila on Thursday afternoon after his namaz-e-janaza, which was attended by a large number of Rohingya people from camps in Ukhiya and Teknaf upazilas.
Formerly a teacher in Myanmar, the slain activist was popularly known as Master Mohibullah among the Rohingya refugees. He was the head of Arakan Rohingya Society for Peace and Human Rights (ARSPH) at Kutupalong camp.
A group of unidentified gunmen killed the 48-year-old man at a refugee camp in Ukhiya on Sept 30.
The Myanmar military launched the operation in retaliation for deadly attacks on border posts claimed by ARSA.
