Nairobi Water and Sewerage Company Managing Director (MD), Nahashon Muguna, snuck out of his office to escape his impending arrest by police, on Monday.
Reports by NTV claimed that the MD left his office abruptly after he was tipped off that National Environment Management Authority (NEMA) officers were heading over to his office to arrest him.
"NEMA's attempt to arrest Nairobi Water and Sewerage Company MD has flopped after the MD was allegedly tipped off and left his office abruptly," NTV tweeted.
NEMA was after Muguna following an exposé aired on NTV, on Sunday, which showed a rot in the entire sewerage system that has left Kenyans exposed to fatal diseases such as cancer.
The investigative journalists spent the past two months with a team of scientists and toxicology experts from the University of Nairobi, tracing Nairobi River from its source at Ondiri Swamp in Kiambu, all the way down its 400-kilometre path to the Kenyan coast.
They then collected various samples of water, fish and crops irrigated using water from the river for testing, with their findings causing panic across the country.
"We tested for the presence of mercury, chromium, arsenic, cadmium, lead, selenium, copper, zinc, manganese, aluminium and barium using a method known as the Atomic Absorption Spectrophotometric (AAS)," Nation revealed.
The shocking results revealed that where one metal was missing, approximately three deadly others were present across the entire span of the river.
NEMA was therefore after the MD over the alarming discovery of unchecked pollution, which has left millions at risk of death.
The lead consultant for the project, Professor James Mbaria - a pharmacology and toxicology expert from the University of Nairobi, revealed that the situation was dire, adding that boiling of the contaminated water had zero effect on the harmful materials.
"Contrary to popular belief, no amount of boiling or cooking of water and food contaminated by these chemicals can stop them from harming the human body. In fact, heating only makes them more dangerous," he disclosed.
"In an effort to clean Nairobi River, NEMA has in the last 100 days arrested 30 people, closed 48 facilities and issued 30 Restoration Orders in Nairobi County alone" Chairman, John Konchelllah announced on Monday.
