Four teenagers have been convicted of hurling stones through a taxi window − and leaving a 70-year-old passenger with a fractured skull.

Shocking CCTV footage from inside the taxi shows the moment a rock smashes through the window, sending glass shards flying through the cab, and striking the woman on her forehead.

Birmingham Youth Court heard how the young people - one aged 15, two 16 and a 17-year-old − pelted at least seven black cabs with stones as they travelled along Bristol Road on 25 May last year.

Below you can listen to how the taxi driver reassures the passengers after being hit.

The three younger defendants all denied involvement but were found guilty of causing wounding and conspiracy to cause damage, while the 17-year-old admitted wounding but was found guilty of conspiracy to cause damage. None of the offenders can be named due to their age.

This investigation has been a long and involved investigation and I would like to commend the community for having the bravery to stand up to the thugs and to come forward. Inspector Steve Rice

The teenagers will be sentenced on February 3rd.
