Police investigating how a woman suffered serious facial injuries when she was struck by a flying fuel cap want to speak to the driver of a flat-deck truck.
The woman was airlifted to Dunedin Hospital after being struck in the face by a flying brass diesel cap while travelling on the Luggate-Cromwell Rd about 3.30pm on Friday.
The fuel cap flew off another vehicle on the Central Otago highway and smashed through the woman's windscreen before hitting her.
She remained in a serious condition at Dunedin Hospital on Saturday.
In a statement on Sunday, police thanked members of the public who had come forward with information.
