A WOMAN was left critically injured and her baby son was also hurt in a hit and run in Birmingham.

The 30-year-old was a passenger in a blue Toyota Yaris, which collided with a blue Audi S3, in Small Heath, at around 11.44pm last night (Friday March 29).

The Audi driver fled the scene of the crash, which happened on Cattel Road at the junction with Arsenal Street.

The injured woman was taken to hospital and was this afternoon in a critical condition.

A man, aged 34, was taken to hospital with minor injuries – along with the couple's one-year-old son.

Det Sgt Paul Hughes, from the West Midlands Police Serious Collision Investigation Unit, said: “This happened on a busy road and I am keen to hear from anyone who witnessed the collision or who recalls seeing the blue Audi just before the collision, on Cattel Road.

“I know from CCTV that there were pedestrians and other cars at the scene who have not yet spoken to us.

“I would urge them to come forward and help us establish the full facts in order to give those involved the answers they need.

“I would also appeal directly to the driver of the Audi to do the right thing and come forward.”

He said the driver may “not have been aware of just how serious this collision was last night” – adding: “But you know now.”

The Audi has been seized and will be forensically examined, as officers follow a number of lines of enquiry to establish what happened.

Anyone who saw what happened or has dash cam footage can email investigators directly at SCIU@westmidlands.police.uk, or via Live Chat on the force website, quoting log 4650 of March 29.
