11.32 PM.

Michael Hopkins was heading home to Graigwen, Pontypridd.

"I was returning home along the A470 from a friend's house in Cardiff, and as I approached the off-slip for the 'Sainsbury' interchange, I observed a single green light apparently stationary over Graigwen. Just after exiting the interchange, I stopped the car and wound down the window to get a better view. As it was 11.32 pm I was not causing a traffic obstruction. I watched the green light, which was, in fact, stationary, for approx 20 seconds or so, when suddenly it turned red and immediately shot off at tremendous speed to the north-east."
