Warwickshire Police is appealing for witnesses following an attempted robbery in Nuneaton earlier this week on Wednesday evening.
At around 4.55pm, it's reported a taxi was driving on Mallard Avenue when a female passenger threatened the driver with a bladed object and demanded money.
An altercation took place and the passenger then ran off along a footpath towards Queen Elizabeth Road, Camp Hill.
No money was stolen and the driver was not injured.
The offender is described as white, short in height, in her mid to late thirties, with short dark hair. It's believed she was wearing a black jumper and black trousers.
