Prosecutor Marius Iacob, in charge with the investigation of the causes that lead to the explosion at the Giulesti Maternity intensive care unit, declared that firefighters detected an improvisation at the AC installation but they cannot say for sure that this is the cause of the tragedy.

The prosecutor declared that the AC installation was checked a week before by a specialized company. Prosecutors obtained an authorization to check the videocameras of the hospital to see how long was the assitant missing from the intensive care unit.
