A SHOOT-OUT on the streets of a sleepy Valencia-province town in the dead of night was the result of an argument about one of the victims' flatulence, police reveal.
A 57-year-old man and his son, 29, suffered gunshot wounds and a man aged 19 and a 16-year-old woman sustained multiple bruising.
They were taken to two different hospitals in the city of Valencia.
Police heard that the two younger men, said to be from 'rival families', were walking down a street in the Xenillet neighbourhood of Torrent, a few kilometres north-west of Valencia, just before the apparent clan warfare started.
One of the men passed wind loudly, but involuntarily, and the other responded by doing the same, except deliberately.
This led to an argument which became very heated and ended in a brawl, and other family members overheard and came outside to join in.
Some were armed, and the two families opened fire on each other.
At least 50 police officers were stationed in the immediate area to prevent further altercations, and two people were arrested for attempted homicide.
