Globally, the issues of extrajudicial killings are on the increase. From racial killings in the West to wanton human rights violations in Africa, the pains are the same. Thus, protests has always been a channel employed by many including activists, labour and union leaders among others, to press home grievances and demands against unfavourable policies and social malaise. This paper draws attention to how youths in Nigeria utilised the physical space to spark a protest, in October 2020. Notable actors, musicians, comedians, activists and the international community in their numbers, moved to the street in defiance of security orders to protest against police brutality and harassment. In view of the outcome of the protest, which was later hijacked by hoodlums, the paper examines a non-violent alternative which can be used to address societal issues. It is in this context that the paper examined the role of theatre as a tool for activism, advocacy and communication with specific reference to street theatre, a type of improvised street drama performance that addresses unfavourable socio-political and cultural issues. The data for the study is obtained mainly from the internet, print media, observations, interviews and literary works. For its methodology, the study utilises the popular theatre approach. The study concludes that street theatre has a major role to play in addressing socio- political issues without resorting to violence.
