How about "I dadnae see the incident"..?
Meaning either ,
"Look - you f**king saw whit happened, and i f**king saw whit happened. If ah say even as much as the ref goat it wrang, I'll get fined and barred fae the dugoot. So take ye mike and shove it, ya wee shite stirrin' dick".
Or
"Aye - oor boay done him. Fair and square. Ah saw it, but amnae gona say that. So take yer mike and shove it, ya wee shite stirring dick".
