From West Midlands Police:
Police are appealing for independent witnesses after a man died following a suspected act of road rage, three weeks to the day since it happened.
The 73-year-old was involved in an altercation with another man on Shenley Lane, Northfield on Monday, 15 September, and later died in hospital on Saturday 27 September.
The man was driving his blue Peugeot 307 estate along the road at around 11.45am and a red Hyundai I20 was travelling in front of him.
Both cars pulled up near the junction of Loftus Close, where the drivers then got out of their vehicles and were involved in a confrontation, during which the Peugeot driver hit his head on the road.
He was taken to hospital with a serious head injury and remained there until his death 12 days later.
Detective Constable Emma Safe is investigating the incident. She said: “We are appealing for witnesses to establish how the man came by his injuries.
“The driver of the Hyundai – a 67-year-old man – has been arrested and continues to help us with our inquiries.
“We are investigating whether the two drivers had been driving in an erratic or aggressive manner further up Shenley Road, at the junction of Meadow Brook Road.
“I would urge anyone who saw either the confrontation on Loftus Road, or anything involving the two vehicles before that, to call us on 101.”
