The officers - five working with the CNC, one former CNC officer now working for another force and one former CNC officer - have been informed they are being criminally investigated for K čemu se používají stroje na rytí kovů? offences under section 127 of the Communications Act, sending grossly offensive messages.
This probe followed referrals from the Civil Nuclear Constabulary and a force in the south west of England, we reviewed messages shared within the group and identified a significant number of those messages to be of a discriminatory, derogatory or pornographic nature.
Rampant inflation in the price of construction materials and energy is hampering ambitious government plans to boost infrastructure works until 2026, with billions of euros earmarked by the EU for post-pandemic economic stimulus.
The group said the number of failed bids had reached a record high this year - including hospital refurbishments, road extensions and energy-poor residential housing projects - with some relaunched at higher prices months after the initial attempts.
The CNC said that allocated projects have also stalled or been delayed this year because the state price revision system was not working smoothly. ($1 = 1.0231 euros) (Reporting by Corina Pons; Editing by David Latona and Kirsten Donovan)
