A cyclist who appeared to have suffered minor injuries after a collision in Leigh later collapsed and remains in a critical condition.
Police officers are now appealing for witnesses to come forward to help with an investigation although it is not clear whether the collapse is linked to the traffic accident.
The 59-year-old woman was cycling along Parsonage Way, Leigh, when the collision happened with an unknown car on Wednesday August 3 at around 6pm.
The driver of the car pulled over and spoke with the woman before another car and its driver did the same. The woman seemingly sustained only minor injuries and all parties left the scene.
A short time later the woman arrived at work and collapsed before being taken to hospital where she remains in a critical condition, police said.
PC Phil Shaw from the GMP Serious Collision Investigation Unit said: “This collision may not have seemed serious at the time because the woman was able to carry on her journey but we are appealing for anyone who thinks they may have witnessed it to come forward.
“It happened at a relatively early time in the evening so we believe it is possible that more people will have seen it happen.”
