Following his arrest, Mwangi produced his press card prompting the officers to make some calls.
The images he had captured were subsequently deleted and he was banned from attending the pass out parade.
“Travelled to Gilgil to attend a relative’s National Youth Service pass out parade. I took pics of the chaos and dirt all over. I was arrested. Produced my press card (I renew my membership every year).
“They made some calls, deleted my pics and said l have been banned from attending the event. The chaos, the dirt, police confiscating food, drinks and throwing everything on the floor.
“No dust bins, no order, and very aggressive language by law enforcers, barking at people. Kenya Police, NYS cadets have sticks to push and hit people,” he wrote on social media.
