Health Cabinet Secretary Aden Duale has urged the government to fast-track the process of investigating and prosecuting all individuals involved in looting and violence during the protests on June 25.

Duale joined a string of leaders who condemned the unrest witnessed in several counties on Wednesday, in a day initially meant for demonstrations to commemorate those who died in similar protests a year to the date.

In his statement, Duale, who briefly served as the Cabinet Secretary for the Ministry of Defence in Kenya, described Wednesday as a 'dark day' for Kenya, adding that several lines were crossed. "The relevant authorities must swiftly bring to book anyone who participated in causing chaos and violence, looting shops and taking away the hard-earned money of Kenyans and destruction of property, including public buildings.

The perpetrators must face the law; the red line was crossed!" Duale said.
