Police are investigating after a suspected dangerous driver who was forcibly removed from his van due to erratic behaviour has died in hospital.
Avon and Somerset Police responded to several calls at around 3.30pm on Friday regarding a van being driven dangerously on Wellsway in the south of Bath.
The Ford Transit came to a stop after crashing into a number of cars.
Members of the public blocked the vehicle with their cars and broke its windows so they could take the keys from the ignition, the force said.
The driver was detained by officers, but concerns for his welfare grew and an ambulance was called to the scene.
A spokesman for Avon and Somerset Police said he was taken to Royal United Hospital in Bath but died overnight.
His next of kin have been informed.
The force said that due to the circumstances of the death, it had alerted the Independent Office for Police Conduct, adding a mandatory referral would be made.
Detective Inspector Keith Smith said: "At this early stage of our inquiry it is not currently clear what happened and what led to the man sadly passing away.
"Our thoughts are with his family at this difficult time and we will carry out a thorough investigation to provide them with the answers they deserve."
Mr Smith added: "While officers spoke to a number of people at the scene we believe there are others who witnessed the incident who we are keen to talk to.
"We'd also like to hear from anyone who drove on Wellsway, Churchill Bridge or Lower Bristol Road yesterday afternoon who has dashcam footage of the incident, as well as anyone who captured it on their phone or private CCTV.
"Similarly, if your vehicle or property has been damaged, please let us know."
Anyone with any information is urged to contact police on 101 quoting reference number 5222143789.
