Authorities say a man from India stabbed two teenagers with a fork, slapped a female passenger and a crew member, and mimicked shooting himself during an international flight. The flight from Chicago to Germany on Saturday was diverted to Boston so that the 28-year-old man could be arrested. He was charged with assault. According to the U.S. Attorney’s Office, a 17-year-old passenger awoke to find the man standing over him. The man stabbed at the teen’s clavicle with a fork and then stabbed another 17-year-old boy in the head, causing a laceration. No attorney was listed for the man in the federal court system Tuesday.
