Additional Inspector General Golam Rasul, who has been standing in for the chief of the Special Branch (SB) of police has been elevated as the chief.
The home ministry issued a notification to this effect on Monday, reports bdnews24.com.
The government has given new responsibilities to 74 officers with the rank of superintendent of police (SP) in three separate notifications on the same day.
Most of them are officers appointed through the 28th BCS exams, along with some from the 27th and 29th BCS batches, as well as those promoted from within the department.
Although they were promoted as supernumerary SPs during the Sheikh Hasina government, they have been working in the equivalent position of additional SP until now.
During the Hasina government, the controversial Additional IG (Grade-1) Monirul Islam served as the SB chief.
Following the change in power, he went into hiding and was later sent on compulsory retirement.
Several cases, including murder, were filed against him.
After the interim government took office in August, DIG Shah Alam was appointed as SB chief.
He was promoted to additional IG on Oct 2 and retired on the same day.
Meanwhile, Gazipur Metropolitan Police Commissioner (DIG) Khondoker Rafiqul Islam was promoted to the rank of additional IG and replaced him.
On Dec 18, Rafiqul was appointed as the head of police's anti-terrorism unit.
After that, Rasul was placed as the acting head of SB as DIG from Dec 19.
A notification was issued on Monday promoting him to Additional IG and assigning him as the current head of the SB.
The service tenure of this officer from the 12th BCS exams will end on Aug 31 of this year.
