“Efforts to establish the full facts and determine all responsibilities are continuing, with the investigation being handled by the Polícia Judiciária criminal investigation police,” Luís Neves’ office said in the same statement. According to the Interior Ministry, “the PSP has strengthened its presence and police visibility in downtown Lisbon and other areas with high concentrations of tourists since June, including through the deployment of Public Order Police officers”. “This increased presence on the ground also contributed to a faster response to Monday’s incident,” Luís Neves’ office added. The ministry said it would also conduct a more detailed assessment of crime in these areas, related activity and the effectiveness of the measures currently available to tackle them. “With that objective, the government, security forces and municipality are working together to ensure the safety of those who live in, work in and visit Lisbon,” the ministry concluded.
