Last weekend I had my phone — an LG Nexus 4 — stolen on a matatu in town (a City Hoppa bus on the Ngong Road → Nairobi route). It must have happened as I was getting off at Kenyatta Ave / Koinange street, as I had it in my hands just before then, but had put it into my bag before alighting. I wanted to go tell Safaricom to block the IMEI so that the phone couldn’t be used on their network, and apparently they won’t do that unless you file a police report.
This is what happened when I went to the Central Police Station to report the theft.
TL;DR: it was an very unpleasant experience; somehow they manage to make you feel like a criminal for being the victim of a crime… (╯°□°)╯︵ ┻━┻
