Nairobi — Senior CID detectives visited the G4S head office to check the cash-in-transit dispatch process after investigations revealed insider involvement in the Sh24 million heist.

Detectives investigating the case have arrested a city lawyer who is reported to have received and hidden the money after the incident, according to an Administration Police officer who surrendered to the police three hours after the incident.

G4S sales and marketing director, Ms Betty Keitany-Koech, on Monday confirmed that detectives visited their offices to investigate Friday's Sh24 million heist.

"There was somebody who came to our office, but they were interested in what happened on Friday," Ms Koech said.

Investigators said the lawyer was supposed to represent those involved in the theft after their arrest.

The detectives intend to conduct an audit of the dispatch process after investigations revealed that G4S staff might have been aware that the van did not have a tracking device and was therefore not being monitored by the control room.

The detectives' visit to the G4S offices comes as Internal Security minister George Saitoti called a stakeholders' meeting to review cash-in-transit services and the security involved. The meeting will be held on Tuesday.

G4S staff are reported to have specifically sought the three APs who had been assigned residential sentry duties and picked them up before the money was stolen.

APs will not be picked up from their residences for escort service as it emerged that the three officers had not been assigned those duties.

At the same time, a policeman attached to a judge was yesterday charged with stealing Sh22 million belonging to G4S.

Mr George Otieno Oguso, who was guarding the judge's residence on State House Road, Nairobi, was jointly charged with two APs Jeremiah Ogendo Nyakweba and Stephen Kipsiele Lang'at.

The three, jointly with others not in court, were accused of stealing the money from Mr Josphat Mwangafwa Kizonguna.

Kibera senior principal magistrate Grace Nzioka declined to release them on bail. She remanded the accused in custody until this Friday to review their bail application.
