The RAB team detained him from Dhaka, said the RAB media wing on Thursday.

On Tuesday evening, Bikash Chandra Das, 18, was injured in a motorcycle accident in Saghata.
Doctors of Saghata Upazila Health Complex referred him to Bogura medical for better treatment.
Sachin Chandra, an uncle of the deceased Bikash, said, "He was first taken to the emergency department. Later at around 10:30pm, Bikash was sent to the third floor surgery department where ward boy Dhulu carried him on a stretcher."
"Dhulu then demanded Tk500 as tips. Since we did not have that much money, Bikash's father Bishnu Das offered him Tk150, but he demanded Tk200. Dhulu got angry and took off the oxygen mask of Bikash."
"The ward boy fled the scene as Bikash stopped breathing. Later the doctor came and declared my nephew dead," Sachin added.
