Ms Brightwood spotted Lewis' camera at the bathroom window in 2018, Wales Online reported today.
She said: 'I went into a state of shock, I didn't really know how to process it. This is not something that people normally have to deal with and I didn't know what to do.
'I am anxious when entering bathrooms as I don't want something to happen to me again. I don't think this is fair.
'Craig is not my biological dad but I treated him like once since age four.'
Lauren is pictured dancing with Lewis when she was a young girl. She said she had looked up to him as a father since the age of four
