AN 83-YEAR-OLD man was airlifted to hospital after falling from his bike in Pinchbeck.
Police are appealing for witnesses because they have not ruled out the possibility he may have been in a collision with another vehicle.
The accident happened in Pennytoft Lane at about 10.20am on Tuesday.
He was taken to Boston’s Pilgrim Hospital and is in a serious condition.
Anyone with information can contact PC Kieran Virth on 101.
