The 206LT TwinStar was a Bell product built upon a PV conversion by Gemini (?) in the mid-1990s. The Gemini project plan was to shut down one engine in flight to save fuel. The CAA were having none of that malarky !
It was trialled by a few UK police forces when owned successively by Textron and Veritair as G-OCOP but it soon became evident that having two engines sucking fuel from the unchanged tank size left it struggling for range. I think the last police user was Gwent.
It went to operate in Spain and I believe crashed lifting out of a bull ring around 1999.
Bell moved on to the 427 in a quest for a light twin.
