A stretch of river has been left 'looking like milk' - with experts probing possible pollution. People living nearby said they were "horrified" after noticing the waters had turned a white colour.
The reason for the change to a stretch of the River Irk, along with nearby Wince Brook, is currently unclear. The Environment Agency has confirmed it is investigating.
One man said he was now scared to walk his dogs and children through the Alkrington Woods in Middleton, Greater Manchester, the beauty spot the river runs through. Chris Turner, 58, told the MEN it was the second time in a week the river had changed colour and said last week it 'looked like someone had put a load of Persil Automatic in it.'
