An accused Kenyan serial killer dubbed “a vampire” and suspected of murdering 42 women has escaped from custody with 12 other detainees, officials said Tuesday.

Mohamed Amin, the head of the nation’s Directorate of Criminal Investigations, said Collins Jumaisi Khalusha of Kenya and other suspects from Eritrea had been allowed to escape from Nairobi’s Gigiri police station with the help of eight officers, including the station commanders.

Officials claim the inmates cut through a wire mesh in their cells and scaled a perimeter wall, with top brass only learning of the escape when officers went to the cells to serve the detainees breakfast.

“Our preliminary investigations indicate that the escape was aided by insiders, considering that officers were deployed accordingly to guard the station,” Amin said.

“This was a high-value suspect who was to face serious charges,” Amin said of Khalusha, 33 — who police have described as “a vampire, a psychopath.”

“We are investigating the incident and will take action accordingly,” Amin said.

The breakout occurred after officials ordered Khalusha to remain under police custody for another week as detectives continued to investigate the 42 homicides linked to him.

Khalusha was arrested in July after authorities were made aware of the discovery of 10 mutilated bodies inside a quarry in Nairobi’s Kware neighborhood.

Officials claim Khalusha confessed to not only killing the 10 women but 32 others within the span of two years, with the first victim being his missing wife.

When he was initially taken into custody, Amin described the suspect as a “psychopathic serial killer who has no respect for human life.”

Khalusha’s lawyer, John Maina Ndegwa, previously told reporters that his client was innocent and that his confession was made after he was allegedly tortured by police.

Ndegwa said he last spoke to his client Friday when the court ordered him to be held for seven more days, with the lawyer baffled over the prison break.

“I’m also confused by the news,” he told The Associated Press.

The eight officers accused of helping Khalusha and the other inmates escape are now facing disciplinary measures, according to acting Police Inspector General Gilbert Masengeli.
