A mysterious explosion in UK's Southampton left residents and netizens shocked as it filled the night sky with spectacular bright flashes of light.
In the now-viral video recorded at St Denys railway station, loud bangs can be heard accompanied by bright flashes of light, and a cloud of smoke bathes the sky in hues of blue and orange.
One of the residents said: "The blast was so bright it looked like daytime," and another jokingly remarked that: "Aliens had invaded Earth."
After an investigation, the transport police department said the explosion was caused by a group of children who chucked a scooter onto the railway tracks which prompted an electrical fault, leading to a big explosion.
The police recovered the scooter from the tracks with the help of a fire and rescue team and after a small disruption while the track was under repair, trains started running smoothly again.
