The owner of the Embakasi killer gas plant Derrick Kimathi and three NEMA officials have been detained at Capitol Hill Police Station pending a court ruling on Wednesday.
The three NEMA officials are Joseph Makau, David Ong'are and Marrian Kioko.
The court is going to rule on whether the three will be detained for 21 days pending the conclusion of the probe into the matter.
The respondents' counsel vehemently opposed their detention saying the fundamental rights of their clients were being violated.
They based their arguments on the presumption of innocent until proven guilty and that the four may end up not being charged after the investigations
The four were on Tuesday arraigned before Chief Magistrate Dolphina Alego with the state seeking detention orders pending completion of investigations.
The 21 days sought is set to allow the Directorate of Criminal Investigations to finish investigations on cases of murder, conspiracy to commit a felony, negligent act causing harm and abuse of office.
Investigation Officer Isaac Tenei told the court that there is fear of the respondents interfering with witnesses and them being a flight risk.
On their part, the prosecution counsel argued that the lives of the four might be in danger considering the loss of lives, properties and injured victims from the Embakasi fire.
They also noted that the matter is one of public interest and it needs to be expedited
