Detectives attached to the Directorate of Criminal Investigation (DCI) arrested a murder suspect in a dramatic pursuit along Nyeri - Nairobi highway on Friday.
In a statement by the DCI, the suspect is said to have been evading the detectives for a week, forcing them to seek help from their digital forensic department.
Sebastian Kamande, 28, is alleged to have murdered his wife and her friend.
He had escaped arrest earlier in Nairobi's Dandora estate after another team of officers was deployed to apprehend him.
"As the investigators from Crime Research and Intelligence Bureau (CRIB) closed in on him at his hideout in Dandora, the suspect escaped the police dragnet," DCI said.
The suspect was later traced to Embu and was cornered along the busy highway as he was returning to Nairobi.
"It was a well-coordinated operation monitored at the Cyber and Digital Forensics operations room."
"The suspect was placed under arrest and transferred to Nairobi," DCI added.
DCI noted that preliminary investigations indicate that the 28-year-old laced the food he had cooked with poison before serving it to the wife and her friend.
"On that fateful day, his wife declined to cook as she was hosting a visitor, prompting the disgruntled husband to prepare the meal," DCI said.
"The suspect laced it with an unspecified poison and served the two women before fleeing."
The suspect will be arraigned on Monday.
