A man from Bristol says he had a rude awakening when his phone received a second government alert warning at 3.49am - over 12 hours after the official test took place.
Liam Moran from Shirehampton said he received the text and siren alert yesterday (April 23) as expected, but was awoken in the early hours of this morning when his phone began making the 10-second warning sound again.
He said: "I got the alarm yesterday at 3pm like everybody else did, and I thought ok, that's normal. Then I got woke up at 3.49am with the same noise, so I knew it was the alarm again.
