On 21 October 2024, Odair Moreno Moniz, a native of Cape Verde and an immigrant in Portugal, died after being shot by a Public Security Police (PSP) officer during a police chase in the Cova da Moura neighbourhood of Amadora. The death of Moniz led to a wave of riots in the Zambujal neighborhood where he lived, which included the looting and arson of two buses. On the night of 22 to 23 October, the riots had spread to six municipalities in the Lisbon metropolitan area, with incidents recorded in sixty police stations in the municipalities of Lisbon, Loures, Amadora, Sintra, Cascais, and Setúbal, which included garbage containers and vehicles being set on fire. Two PSP officers were injured by stone throwing and received hospital treatment.
