Strange symbols have been spotted in West London.
Reader Maria Speechley spotted one at the junction of Grove Road, Uxbridge and Grove Way.
There is another of the white, spray painted symbols in the pedestrianised section of Uxbridge High Street, close to Lloyds Bank.
The mark – a square central dot with radiating triangles – resembles a windmill’s sails or a stylised sun.
Harrow police confirmed last week how criminals in their area have been using coded symbols to indicate properties or areas worth investigating for burglary.
Speechley seems to jump right to conspiracies though as she asks whether it could be a landing site for aliens or some kind of secret message. Although she might also just play this up for laughs.
If the police are correct, it might indeed be a secret message but for thieves and burglars, not aliens.
Or do we have another Toynebee tiles mystery on our hands?
