From the BBC news website.
A helicopter has crashed near an estuary in north Lancashire.
Police said a may day signal was sent from the aircraft as it flew over Poulton-le-Fylde, near Blackpool, at about 1210 BST.
About 45 minutes later, an aircraft was located at Barnaby's Sands, an area of salt marsh on the edge of the Wyre estuary.
Two people were believed to be on board but the extent of their injuries is not yet known.
Emergency services are at the scene and are carrying out a recovery operation.
