He removed two officials, the prison director and the head of the police investigations unit, and replaced the head of the national police with Cesar Augusto Zapata Correa, a long-time member of the force with nearly 35 years of experience.
The announcement came after six inmates were killed at the Litoral Penitentiary on Friday and another was killed in a Quito prison on Saturday.
Another prison official in charge of the prison where the six were killed was taken into custody for questioning, according to the president’s announcement. Lasso also ordered the transfer of six inmates implicated in Villavicencio’s murder for their security.
Violence, blamed by the government on drug gangs, has sharply increased in Ecuador in recent years and the latest killings seemed to underline rising lawlessness.
Ecuador’s attorney-general’s office also launched an investigation into the country’s prison agency, the office said earlier on Saturday.
Prosecutors said they initiated the investigation because the agency, SNAI, did not carry out a pending order to transfer for security reasons the six inmates killed at the Litoral Penitentiary on Friday.
Villavicencio, a prominent journalist who exposed corruption and organised crime, was gunned down while leaving a campaign event in August. Police arrested six people and killed one suspect on the same day. Another seven suspects were later arrested.
Lasso was meeting with his security cabinet on Saturday and cancelled an upcoming trip to South Korea to “address the crisis in the penitentiary system,” according to his official social media account. The government has previously promised to identify the intellectual authors of Villavicencio’s murder.
Villavicencio built his career on exposing corruption by politicians and business leaders and before his death had denounced both the Albanian mafia and a leader of the Los Choneros gang who goes by the alias Fito.
Ecaudor’s interior minister said on Friday that an investigative police report into Villavicencio’s killing was ready. The report has not yet been made public.
The second round run-off vote will be held on Oct 15.
Both candidates, business heir Daniel Noboa, who is narrowly leading polls, and leftist Luisa Gonzalez, have demanded that the government clarify information about the prison killings.
The killings of the suspects are unlikely to affect voting intentions for the second round, political analyst Alfredo Espinosa said. However, clarity about who is responsible for Villavicencio’s murder could, especially if a politician were to be found to be involved, lead to “an ethical and moral shake-up in the country,” Espinosa said.
