Detectives are trawling through CCTV footage to try to identify who hurled a brick through a taxi window, leaving a toddler with serious head injuries.
The two-year-old girl was left with a deep wound to the back of her head which was bleeding heavily after the house brick smashed through the rear window of the cab.
She was travelling with her mother along Dudley Road in the Wednesbury area of Sandwell when the brick was thrown.
Det Cons Debbie Hickinbottom said the child's 26-year-old mother has been left "deeply shaken" by the attack.
Fortunately the child was not permanently harmed and she has made a speedy recovery.
However the incident has left her mother deeply shaken.
We are checking local buildings for CCTV, but meanwhile we are hoping that a member of the public may have witnessed something which will lead us to the culprit.
