The Uttar Pradesh Police on Sunday suspended two policemen from the Jamania police station for indiscipline, The Indian Express reported. Action was taken against them for wearing black armbands to protest against the arrest of two constables in connection with the murder of Apple executive Vivek Tiwari in Lucknow last week.

Tiwari sustained a fatal bullet injury to his neck when one of the constables allegedly fired at his vehicle after it drove into a patrol motorcycle.

“Today we were informed that some policemen at the Jamania police station were wearing black armbands,” Ghazipur Superintendent of Police Yash Veer Singh. “Action was taken against them. Constables Keshav Dutt Pandey and Mohammad Shadab Siddique were suspended. Eleven other policemen, including Akhilesh Kumar, who was in charge of the station, were sent to police lines.”

On Friday, the state police had sacked three station house officers for lack of supervision, suspended three constables for wearing black armbands and arrested two former policemen for inciting colleagues to protests against the arrests of the murder accused.
