The Boston Globe’s Marc J. Spears is reporting backup guard Tony Allen —- 0 points, 3 rebounds in Boston’s 107-86 Game 3 defeat of the Bulls last night — has been the target of death threats in Chicago, and required additional security surrounding the Celtics’ bench Thursday evening.

Sources said Allen has been receiving the threats in Chicago for some time. The former Crane High star also received threats prior to a March 17 game at Chicago, sources said, but he didn’t make the trip because of a thumb injury.

“Is that what you’re going to write about? Is that what you’re going to write about?” said Allen, before walking away after being asked about the threats.

On April 25, 2007, Allen was found not guilty of aggravated battery in a Chicago court. The ruling came on the second day of a trial stemming from a fight in August 2005 outside a Chicago restaurant. The fight escalated into a shooting at the White Palace Grill in the West Loop Aug. 28.
