James “Whitey” Bulger, the alleged mob boss who is set to go to trial next year, is reportedly being treated at a Boston hospital tonight.


Bulger, 83, was taken from the Plymouth County Correction Facility, where he is being held, to Boston Medical Center Sunday afternoon, according to WBZ-TV. He apparently complained of chest pains, WBZ reported.


Officials from the U.S. Attorney’s Office and the U.S. Marshals Service said they could not comment.


Bulger is awaiting trial after living on the run for more than a decade. He was arrested last year in Santa Monica.


His attorney argued last week in court that the trial should be delayed from March to November because of the thousands of documents of discovery evidence that needs to be reviewed. A judge has not yet ruled on that matter, but a decision is expected this week.

The push to delay the trial has angered some family members of Bulger’s alleged victims and they consider the move a stall tactic. Some have previously expressed concerned about the aging Bulger's health.
