ORLANDO, Florida (Reuters) - Golfer Tiger Woods' Swedish mother-in-law was taken from his Florida home by ambulance to a nearby hospital early on Tuesday suffering from apparent stomach problems, officials said.

Details were not immediately available. But the incident was bound to prompt fresh media speculation about the private life of Woods, the world's No. 1 golfer.

He has been under intense media scrutiny since being injured in a minor car accident in the middle of the night outside his home late last month.

He has since admitted to "transgressions" that apparently addressed allegations of marital infidelity.

"Barbro Holmberg, mother of Elin Woods, was admitted to Health Central Hospital with stomach pain," said hospital spokesman Dan Yates.

"She's in stable condition and is undergoing current evaluation still," Yates told reporters.

Yates did not elaborate but local television said medics were called to Woods' home in Windermere at 2:36 a.m.

After Holmberg was taken to the hospital a younger looking blond woman arrived there in a black Cadillac Escalade SUV.

A witness told WSVN, a local Fox television news affiliate, that the woman in the Escalade, who appeared at Health Central Hospital shortly after the ambulance had arrived, appeared to be Woods' Swedish wife, Elin Nordegren

The golfer's car accident last month triggered widespread speculation about his private life, given the time it happened and his refusal to meet with police to answer questions about it. Media outlets have reported Woods has had extra-marital relationships with up to six women, maybe more.

Companies whose endorsements have helped make Woods perhaps the world's richest athlete, with a fortune estimated at $1 billion, have said they are standing by him.

His mother-in-law is a former government minister in Sweden who is currently governor of Gavleborg County.
