Police -  In 1928 cattle thieving, especially in areas adjacent to the pastoral tribes, also began to increase. It was believed that many of the cattle stolen from farms on the Uasin Gishu Plateau, Lumbwa and the Upper Rift Valley had been driven into the extensive forest region to the north of Londiani. A round-up was organized. Superintendent R.F. Rainsford was placed in charge of the operation and assisted by Superintendent E.K. Catchpole, Asst. Superintendents H.C. Croysdale and J.G. Leslie, 8 other European officers, some 200 African Police, and a few African guides and trackers. The forest was encircled and entry started simultaneously from 9 different points on its fringes. The operation proved highly successful. On the Lumbwa side 2,500 head of cattle were rounded up, and on the Eldama Ravine side 2,000 head were found with the Wanderobo when they should not have had more than about 700. It had been tough but rewarding work, while the cattle-rustlers were taught a salutary lesson.
