Battle of the blue-rinsers: Gangster granny unleashes vandalism hell against couple

An elderly couple have been ‘devastated’ by a mystery vandal who destroyed their cars with paint stripper, and then returned ten months later to push manure through their letterbox.

Ken and Diane Lott, both 81, returned home from holiday on February 8 to find a poo-like substance all over the front door and a key glued into the key hole.

The couple have no idea why they are being targeted by the unknown figure, who the police are scrambling to identify.

The vandalism began in April last year, when Ken and Diane came back from a holiday with their daughter Julie, 48, and found paint stripper all over their two cars.
