The search for a missing helicopter with five people on board was called off last night due to poor visibility.

The private craft went missing over the Irish Sea 

The search and rescue operation is focused on the area between Caernarfon Bay, north Wales, and Dublin

The craft went missing yesterday, but no mayday or distress call was received

The UK Coast Guard has called off the search, as "due to low lying cloud, visibility has been extremely poor and has hampered the search efforts."
