BBC presenter Ashley Blake has been convicted of wounding a teenager with a large wooden pole at a pub in Sutton Coldfield.
CCTV video showing the events leading up to the attack have now been released.
Midlands Today reporter Blake was found guilty of unlawful wounding at Birmingham Crown Court after swinging a patio umbrella pole above his head and striking 17-year-old Greg Jones in the face at an 18th birthday party at the pub Blake then owned, The Place 2B.
The 40-year-old, who also works on the Inside Out current affairs show, was also found guilty of intending to pervert the course of justice by throwing the pole into a neighbouring garden centre in an attempt to conceal it from police.
Judge Peter Carr warned Blake he faced a possible jail sentence. He told him: "You have been convicted of a serious offence which involved wounding a young man.
"The almost inevitable outcome for a case such as this is a prison sentence and I warn you that that is the most likely outcome."
