When asked by MTI, the communications department of the Fejer County Police HQ said police received information in the evening on Friday that a number of people were making preparations for illegal activity. In the interest of maintaining order in public areas, the HQ said an appropriate number of police officers took steps, checking IDs and vehicles.

In a single instance, police launched a procedure for a violation involving possession of a particularly dangerous device, but the HQ said there was no suspicion of criminal activity and orderly flow of traffic was restored.

Dunaferr said on its corporate website that it had learned a group of "mercenaries" recruited to represent the interests of the Ukrainian Tatyana Taruta, Dunaferr's minority owner, had made preparations "to occupy the steelworks".

The dispute between Dunaferr's majority Russian owner and Ukrainian minority owner has been ongoing for about a year.
