The FBI is observing the 79th birthday of fugitive mob boss James "Whitey" Bulger by doubling the reward for information leading to his capture to $2 million.

The former head of Boston's notorious Winter Hill Gang fled in January 1995 after being tipped by a former FBI agent that he was about to be indicted on federal racketeering charges.

Bulger was later charged in connection with 19 murders and is on the FBI's "Ten Most Wanted" list.

The FBI announced the new reward on Wednesday in Boston with federal prosecutors, Massachusetts state police and state prison officials.

Bulger also was an FBI informant. Authorities say he gave the FBI information on his gang's main rival, the New England mob.
