What thwart the police's chopper plans?

It appears that the order for the acquisition of fresh helicopters did not go according to police plans. The formation was to get 4 Bell 407GXi machines straight from the manufacturer, as part of a free-hand acquisition procedure. However, the negotiations were most likely not successful, given the fact that a fresh procedure involving the acquisition of 4 single-engine helicopters appeared on the website of the Police Headquarters.
