A police Inspector of Chattogram Metropolitan Police (CMP) was assaulted by a sub-inspector and later handcuffed in the port city's Riazuddin Bazar area.
The incident occurred on October 25 evening at Hotel Paramount City, when SI Robiul Islam of Kotwali Police Station beat up Inspector Aftab Hossain of Counter Terrorism (CT) Unit of CMP.
On Thursday night, inspector Aftab lodged a written complaint to CMP Commissioner against SI Robiul in this connection.
Accused Robiul is the in-charge of CRB Police Outpost under Kotwali Police Station, said police sources, adding that the incident took place over a misunderstanding while investigations for another complaint was ongoing.
On October 22, an entrepreneur named Nur Mohammed (65) was allegedly mugged of Tk 2.90 lakh by men disguised as Detective Branch (DB) of police officials from the port city's Kadamtali area.
The victim filed a complaint with Kotwali Police Station and SI Robiul was asked to investigate the matter.
On October 25, Nur Mohammed and his sons called SI Robiul over the phone saying they spotted the muggers on the ground floor of Paramount City, said police sources.
Robiul, along with ASIs Anup and Rubel and a few constables rushed to the spot where Nur Mohammed and his sons pointed out Inspector Aftab and one Hasan as the muggers.
Without asking anything, Robiul handcuffed Aftab. When Aftab resisted, SI Robiul punched him in the face, added the sources.
After Aftab identified himself and showed his wirelesses set and ID card, the SI removed the handcuff and later took Aftab and Hasan to Kotwali Police Station, witnesses said.
CMP Commissioner Saleh Mohammed Tanvir told The Daily Star, "After investigation, we confirmed that Inspector Aftab was not involved with the incident, and he was in his house at the time of the alleged mugging."
