Police are appealing for witnesses following the death of 90-year-old driver Richard Tredgold, who was involved in a collision in Lancaster last month.
Around 10.40am on Wednesday 18th September, a Ford Fiesta and a Vauxhall Frontera collided on Wyresdale Road at the junction of Littlefell Lane.
Mr Tredgold, who was driving the Fiesta, was taken to Royal Lancaster Infirmary with what were initially believed to be minor injuries. However he died in hospital on Saturday as a result of his injuries last week.
The driver of the Frontera did not suffer any injuries.
Sergeant Malcolm Bell said: “Initially we believed Mr Tredgold to have suffered only minor injuries, but sadly he passed away yesterday.
“The circumstances surrounding this collision are being investigated and I would urge anyone who witnessed it or has any information about it to contact police.”
