Police are warning of the dangers of laser pens after teenagers were seen shining a pen into people’s faces in Queen Street.

Thames Valley Police said the boys were spotted shining the intense beam of light into the faces of cyclists, pedestrians and bus drivers between 2.30pm and 2.45pm last Monday.

Pc Ben Simmons said: “It was a busy time as the streets were full of Christmas shoppers and if any of the victims had been temporarily blinded by the pens, especially the bus drivers, there could have been a terrible accident.”

A 17-year-old arrested in connection with the incident was bailed until January 14.
