Police have urged the occupants of a car involved in a crash which left a two-month-old baby dead to come forward.
West Midlands Police said at least four people who were travelling in a Mitsubishi Evolution left the scene of the collision before officers arrived.
The silver Mitsubishi, which has no registered owner, crashed with a Toyota Corolla on Grove Lane in Smethwick, West Midlands, shortly after 6pm on Saturdaay.
The baby boy, a passenger in the Toyota, was taken to Birmingham Children’s Hospital but could not be saved and was pronounced dead shortly after arrival.
A 24-year-old woman travelling in the same car received multiple injuries and remains in hospital in a critical but stable condition.
Three more passengers from the Toyota – two men, aged 27 and 69, and a 26-year-old woman – were also injured in the crash, police said.
A spokeswoman said: “It is believed at this stage that there were at least four people travelling in the Mitsubishi. All left the scene following the collision and prior to police attendance.”
Inspector Mark Watkins, from the force traffic department, said: “I would again appeal to anyone who can provide any information regarding the Mitsubishi, registration number R54 RMW, or its occupants and I would like to make a personal appeal specifically to those occupants to contact police.”
West Midlands Ambulance Service said five ambulances, a rapid response vehicle, a doctor and an incident support officer attended the scene of the collision.
Anyone with information is urged to contact West Midlands Police on 0345 113 5000 or to call Crimestoppers on 0800 555 111.
