The Prosecutor-General's Office (PGO) and the Security Service of Ukraine (SBU) have conducted searches in the offices of the national railway operator, Ukrzaliznytsya, in the case of procurement of an unfit refrigerant for air conditioners in passenger cars.
The PGO said in its Tuesday statement that in the early summer, a division of Ukrzaliznytsya concluded a 3.8m-hryvnya contract for the purchase of 7 tonnes of refrigerant.
"According to an expert conclusion, the delivered substance is not suitable for use in air conditioning systems of passenger trains," its statement reads.
During the searches, law enforcers confiscated technical documentation and over 45 cylinders with an unknown substance, which, according to accompanying documents, is a refrigerant.
Ukrzaliznytsya officials involved in the undue procurement may be charged for abuse of office and forgery.
In August, Ukrzaliznytsya broke the contract with a contractor which maintained air conditioning systems after Deputy Prime Minister Ivanna Klympush-Tsyntsadze complained about stuffiness in a passenger train.
