He said he was informed that there were “one or two civil servants”, believed to be lecturers who were involved in the rally.

“Their participation was detected through CCTV cameras and also photographs shared on social media.

“I have asked the relevant ministries if their officials were involved. However, this will be verified. We cannot simply go after them,” he told reporters after attending the Public Sector CIO Convex 2016 conference here yesterday.

Ali said action would be taken against civil servants who were involved in the rally, depending on the offence committed.

Last week, he reminded civil servants not to participate in any rally which had not been given a permit, and if they did, they could face disciplinary action, including sacking or a salary cut.
