Infamous Boston mobster James “Whitey” Bulger was taken to a hospital early Monday morning after complaining of chest pains.

Bulger, 83, is set to stand trial March 4 for his alleged involvement in 19 murders. His lawyers are trying to push the trial to November 2013.

Firefighters with the Plymouth Fire Department arrived at the Plymouth County Correctional Facility in Massachusetts around 1:48 a.m. to take Bulger to Boston Medical Center, Kevin Murphy, the fire department’s battalion chief, told the Boston Globe.

Murphy would not disclose why Bulger, the former leader of Boston’s Winter Hill Gang, was taken to the hospital, although sources told the Globe that the Boston mobster was complaining of chest pains.

The hospital visit marked the second time Bulger sought medical attention away from the Plymouth jail this year.

He was checked out at a Boston Hospital in December, although officials would not say the reason for the hospital visit, the Globe reported.

Bulger’s lawyers argued Friday for his trial to be pushed back. During the court appearance, the families of Bulger’s alleged victim expressed their concerns over the Boston gangster’s health, according to the Globe.

Bulger’s lead attorney, J.W. Carney, argued that prosecutors have been slow in releasing documents to him and claimed he won’t be ready for a March trial, the Associated Press reported.

The mobster’s legal team is poring over 300,000 documents related to the case, according to the AP.

Prosecutors are countering Carney’s claims by maintaining the lawyer is just stalling, the Globe reported.

Bulger was captured in Santa Monica, Calif., in June 2011 after being on the lam for 16 years following an FBI blitz of a public service announcement campaign that targeted 10 states where the feds believed Whitey may have been hiding. California was one of those states.

Whitey Bulger eluded authorities due to help from girlfriend Catherine Grieg, who was sentenced to eight years in federal prison earlier this month for her role in harboring the fugitive and reputed Boston mobster in Santa Monica.

A lawyer for Grieg said she had no regrets because she was in love with the guy and lived with him for 16 years.
