The FBI said a tipster who led federal agents to the California home to Boston mob boss James "Whitey" Bulger and his longtime girlfriend recognized the couple from a recent TV campaign.

FBI spokesman Greg Comcowich said the tipster called the FBI after she saw the recent commercials that ask people, particularly women, to be on the lookout for Bulger's girlfriend, Catherine Greig.

The commercial said that Greig had several plastic surgeries before going on the lam and was known to frequent beauty salons. The 30-second ad ran this week in 14 television markets.

Comcowich said the FBI won't disclose the tipster's identity or say where the tipster called from.

The FBI was offering a reward of up to $2 million for information leading to Bulger's capture _ the largest ever offered for a Top Ten domestic fugitive _ and up to $100,000 for Grieg's capture.

The 81-year-old Bulger is wanted for numerous crimes, including 19 murders. He appeared in a Boston federal court Friday.
