A large-scale police operation is under way after a high-performance Audi was carjacked with a four-week-old baby girl on the back seat.

Dozens of officers have been deployed to search for a grey Audi A3 S-line, registration BJ66 YLV, in connection with the incident, West Midlands Police said.

The alarm was raised after the car was targeted in Marie Drive, Acocks Green, in Birmingham, just after 4pm on Thursday.

It is believed the car may have been travelling towards Solihull, West Midlands, when last sighted.

Police have urged members of the public to keep an eye out for the baby girl over fears she may have been abandoned by those in the car.

In a statement, the force said: “Extensive police resources are looking for the car and are asking you for help – call us on 101.

“We believe they travelled towards Solihull.

“We would also ask you to look out for the child in case the offenders have realised what they have on board and abandoned her.

“Our priority is the baby’s safe return.”
