For more than three hours, police carried out door-to-door searches of nearby residential buildings, looking for sympathizers of Somali militant group al-Shabab. Police demanded everyone produce identification cards and searched people's rooms. Multiple of these arrested were Somali refugees who are required to have alien cards issued by the Kenyan government. Kenyan officials have ordered Somali refugees living in urban areas to return to designated camps, following a wave of terror attacks and threats in the country attributed to al-Shabab. The country's security officials have warned there will be more arrested until those behind Monday's attack are found.
