Sharmaine Lincoln, the mother of a teenage boy who died after being shot and stabbed in Birmingham, has asked the public for help in finding her son's killers.

A group attacked 15-year-old Keon at about 3.30pm on 21 January in the Handsworth area of the city, according to West Midlands police. Witnesses said shots were heard and the suspects were armed with knives.

'I just need help, come forward, to not let Keon's death be in vain,' said Ms Lincoln. 'Help bring justice, a bit of closure.'

A number of teenagers have been arrested in relation to the case.
