agbero
n.— «While the officials were preventing drivers from making unnecessary U-turns, the agbero was said to be encouraging them and even directing them to drive against traffic. The excesses of the miscreant reached such a point that he was stopping vehicles on the middle of the bridge, molesting and extorting money from drivers and conductors, thereby compounding the already chaotic traffic situation.» —“Agbero, 6 Traffic Management Authority Men in Street Fight” by Anthony Okoro in Lagos, Nigeria All Africa July 22, 2002.
