Knife Wielding Man Shot at Chik-Fil-A in Boston

An off-duty Boston Police officer shot and killed a man who was armed with a knife inside a Copley Square restaurant Saturday, according to police.

Boston Police Commissioner Michael Cox said the officer took action after the suspect, wielding a knife, chased two people into the Chik-fil-A restaurant on Boylston Street.

"The off-duty officer identified himself as a police officer, instructed them to drop the weapon, at which point the individual did not comply. The officer discharged his weapon to stop the threat and the individual was struck," Cox said.
