Three individuals, among them KANU Secretary General George Wainaina, have been arrested in connection with the murder of lawyer Mathew Kyalo Mbobu, who was shot dead on Magadi Road on Tuesday.

For a second day running, investigators probing Mbobu’s assassination have been questioning suspects believed to hold vital details that could shed light on the case.

The three were initially interrogated on Thursday and are now being held at different police stations across Nairobi.

Two of them, described as close associates of the slain advocate and said to have been with him during a lunch-hour meeting, are detained at Kilimani and Capitol Hill Police Stations.

Wainaina’s lawyer confirmed his arrest, clarifying that he was picked up as a person of interest. After being questioned, he was taken to Kileleshwa Police Station but was later rushed to the hospital for treatment.

“There is an active investigation that is going on, and it’s not only him. We have been told it is a homicide investigation, but we don’t know which one,” said Wainaina’s lawyer, Maulid Musa.

Although detectives have not disclosed the specific role of the three suspects, they believe the trio may be crucial in tracking down the gunman and the motorcycle rider who escaped after the shooting.
