Coronation Street Barbara Knox's daughter banned from driving.
Knox herself was also arrested on suspicion of drink-driving after driving to Knutsford Police Station to enquire after her daughter.
According to reports, Maxine Ashcroft, 56, has been banned from driving for two years after failing a breathalyser test while driving her mother home following an afternoon out.
Ashcroft was said to have been three times over the legal limit at the time of her arrest.
Knox - who plays Rita Tanner on the ITV soap - was reportedly bailed from police custody pending further enquiries.
A Coronation Street spokesperson declined to comment, saying: "This is a personal and private matter."
