Bam Margera Hauled Off by Cops in Finland

Breaking News

Bam Margera spent a night in a Finnish drunk tank after getting into an argument with his wife.

Helsinki cops tell TMZ ... they detained the "Jackass" star on Sunday night outside the Sea Horse -- a landmark restaurant in that city. Witnesses say things were getting heated between Bam and his wife, Nicole ... when cops arrived and hauled off Bam at 11 PM.

We're told he was not booked for any crime, and they just let him sleep it off until 6 AM Monday.

Bam and Nicole have a rocky past with booze. As we reported, she got busted for DUI earlier this year, and wrecked their Porsche.
