Oslo, Norway ? British singer-songwriter Amy Winehouse was arrested in Norway for marijuana possession and held overnight, a police official said Friday.

Winehouse and her husband, Blake Fielder-Civil, were released Friday morning after paying $715 each in fines, prosecutor Lars Morten Lothe said. A third person, also released, was fined $492, he said.

The three were arrested shortly Thursday evening at a hotel in Bergen in southwestern Norway, where Winehouse is on a European tour, after a tip to police.

“They were found with seven grams (about 1/4-ounce) of marijuana,” Lothe said. “She’s paid the fine, so this thing is over for us now.”

Winehouse was to perform in Oslo today, before heading to the Netherlands on Monday.
