Rampage at VW dealership ends with man swilling champagne on truck roof

He was sober, drug-free, with no criminal record and he passed a late-night mental competency test.

Nor, as far as is known, had the man had any prior dealings with the target of his wrath, the Roseland Volkswagen Dealership in Burlington.

So what prompted him to drive on to the dealership lot and launch a one-man demolition derby that culminated in his standing on the roof of his truck, swilling champagne, urinating on the parked cars around him and hurling debris at an astonished tow-truck driver who happened by?

The folks at Roseland don't have the least idea. Likewise Halton Regional Police, who arrested Guillaume Mercier, 38, of Hamilton shortly before midnight on Monday and charged him with mischief and indecency.
