Heroes on Malaysia Airlines Flight MH128, bound for Kuala Lumpur from Melbourne, took down a man who allegedly made a false bomb threat. A witness told BBC how passengers tackled the man, allowing police to arrest the passenger immediately upon landing. The plane was forced to return to Melbourne after the suspect, a 25-year-old Sri Lankan man, claimed to carry an explosive device onboard. Police said the incident was not terror-related and determined that it was a case involving a mental health issue.
