A murder investigation is under way after a man in his 50s was stabbed to death in Castle Bromwich.
It's believed the victim had been travelling in a car which was rammed by another vehicle.
He was then attacked by a number of people who then fled from the scene.
In a statement, West Midlands Police said: "We were called to Chester Road just before 8.15pm yesterday (18th April).
"A man in his 50s was found with serious injuries and sadly nothing could be done to save him."
The force continued: "We're carrying out extensive enquiries to establish exactly what happened and why and to identify those responsible."
Dave Sanders, of West Midlands Police, added: "We're supporting the man's family during this deeply distressing time.
"I'd like to hear from anyone who saw what happened or who was in the area at the time and may have dash cam footage to please get in touch.
"It could be vital to our investigation."
