OCOEE, Fla. — Tiger Woods' mother-in-law was admitted to a hospital with stomach pains early today, a hospital spokesman said.

Someone called 911 from the golfer's Orlando-area mansion about 2:35 a.m.

Barbro Holmberg, the mother of Woods' wife, Elin, was taken by ambulance to Health Central Hospital, where she was in stable condition today, hospital spokesman Dan Yates said. He said her condition was not serious but he could not be more specific because of privacy laws.

Holmberg, who lives in Sweden, arrived in the U.S. a few days ago.

Yates said Holmberg was in a private room and the family has hired additional security to keep the media away. He said family members have visited her, but he would not say who.

"She's in a wing that helps protect her privacy," Yates said.

Media attention has been focused on the world's No. 1 golfer since he hit a hydrant and a tree around 2:25 a.m. on the Friday after Thanksgiving.

The Florida Highway Patrol last week cited Woods for careless driving and fined him $164.

The accident — and Woods' refusal to answer questions about it — fueled speculation about a possible dispute between him and Elin.

Just days before the crash, a National Enquirer story alleged Woods had been seeing a New York nightclub hostess, Rachel Uchitel, who has denied it. After the crash, Us Weekly reported that a Los Angeles cocktail waitress named Jaimee Grubbs claims she had a 31-month affair with Woods.

Last week, Woods issued a statement saying he had let his family down with unspecified "transgressions" that he regrets with "all of my heart." He did not elaborate.
