Police are appealing for witnesses to reports of a driver who threatened another driver in Langley Mill.
The incident happened just before 1:15 pm on Monday 28 March, on Derby Road, just off a roundabout from the A610.
A driver said they were coming off the roundabout when a blue coloured SUV type vehicle pulled in front of him.
Both vehicles stopped and a man then allegedly got out of the blue car and came over to the driver and made threats towards him while holding what was thought to be a wrench.
The area would have been busy around that time and would like to speak to anyone who may have seen the incident, have dashcam footage or with any information which could help with enquiries.
If you think you can help, please contact Derbyshire Police on 101 reference 22-178545
