What did the widow do to the police and the County Council officials?

Now here is the news.
    Last night, for the third time this week, police and the County Council officials had to turn and run when they were showered with boiling water from the upstairs window of No. 10. Trafalgar Street. They were hoping to speak to Mrs. Florence Hamilton, an 83 year-old widow, who is still refusing to leave her home. Every other house in the street has been demolished, the Council are planning to build four 20-storey blocks of flats in the area. All the other residents agreed to move when the Council offered to provide them with new flats nearby. On Tuesday evening a social worker who wanted to speak to Mrs. Hamilton was attacked and badly bitten by one of her dogs.
