Police officers spotted the 56-year-old actor-comedian early Sunday in the slow-moving vehicle and noticed he smelled of alcohol when they pulled him over, said Detective-Inspector Christer Holmlund of the Stockholm police.
"He refused to blow in the (breath test) instrument, citing American legislation," Holmlund told The Associated Press on Wednesday. "So we applied the old method — a blood test. It will take 14 days before the results are in."
"Then he was let go. My guess is he went back to America," Holmlund said.
He said Murray would only be charged if tests show his blood alcohol level exceeded the legal limit, which is quite low in Sweden.
A very high alcohol level could lead to a prison sentence, but Holmlund said fines were more likely.
"There were no obvious signs, like when someone is really tipsy," he said.
Holmlund said it wasn't clear where Murray picked up the vehicle, or to whom it belonged.
"It was a golf cart. How it ended up in this predicament I don't know," he said, adding that Murray wasn't facing any theft charges.
It isn't illegal to drive a golf cart in city traffic in Sweden, but Holmlund said it is very unusual.
"I have done this since '68 and I've never experienced anything like this," he said.
Murray was among the cast members on NBC's "Saturday Night Live." He was nominated for an Oscar for 2003's "Lost in Translation." His screen credits also include the 1980 golfing comedy, "Caddyshack"; "Groundhog Day"; and "Rushmore."
