EDEN PRAIRIE, Minn. - Investigators are looking into a party attended by several Minnesota Vikings players that allegedly involved drunkenness, nudity and visible sexual activity on a pair of charter cruises last week.

No criminal charges had been filed, and it could take a couple of weeks before investigators finish interviewing people who were on the boats, said Sgt. Haans Vitek of the Hennepin County Sheriff's Office. A police report was filed Sunday.

Stephen Doyle, an attorney representing the boats' owners, has said cornerback Fred Smoot paid for one of the cruises last Thursday on Lake Minnetonka. He said about 90 people were on the boats, which returned to shore more than two hours earlier than scheduled when crew members complained about lewd behavior.

Smoot said he was planning to take legal action against whomever "put my name in there."
