Chinese outlets report a paper company, clothing-maker and food coloring manufacturer all lie along the river and could have something to do with the incident.
China News quotes the city's chief of the environmental protection bureau, who said, "We suspect that somebody dumped artificial coloring in the water because he thought the typhoon yesterday would cause heavy rain, and nobody would notice [the color] ... It turned out there wasn’t heavy rainfall yesterday, so the evidence is left behind."
This incident mirrors a 2012 phenomenon when China's Yangtze River turned a similar bloody tinge. (Via International Business Times)
According to the Daily Mirror authorities claimed that incident was the result of sand distribution from upstream flooding.
And mysterious pollution in China has made headlines for years.
