On Wednesday (5/5) a man was stood by the side of a HGV in Jones Barn Farm Hill, when it is believed a green laser was shone towards him.
It happened at 2.15pm at a HS2 construction site in Wendover.
He turned towards the light source, which then went into both of his eyes, causing his vision to be impaired and prevented him from working. His eyesight remained impaired and blurred for 15 minutes, and he has since suffered pain in his eyes.
The victim - a man in his fifties - has received hospital treatment since.
Two other people in the area also noted that they had a laser shone towards them, however they did not sustain any blurred vision or injury.
A Thames Valley Police spokesperson said: “This incident was a dangerous act, which resulted in a man aged in his fifties sustaining blurred vision and also pain in his eyes.
