“You can contact us anonymously via Crimestoppers if you don’t want to speak directly to police, but please do get in touch. A man was seriously injured in this incident and it is important that we have clarity on the circumstances leading up to, and immediately following, the incident.
“If you were there, even if you don’t believe you have anything of value to add, please do get in touch.”
