The FBI is investigating the stabbing of a police officer at Flint, Michigan’s Bishop Airport as a ‘possible act of terror,’ according to reports. 

A Canadian man yelling ‘Allahu Akbar’ repeatedly stabbed the officer including in the neck at the airport on Wednesday morning, witnesses told NBC News. 

The saying means ‘God is great’ in Arabic, and is often shouted by Islamic terrorists before attacks or suicide bombings. 

The police officer involved in the incident has been identified as Lieutenant Jeff Neville, who is retired from the Genesee County Sheriff’s Department.  Sheriff Robert Pickell told WJRT that Neville was an ‘amazing deputy’. He has reportedly worked as an officer at the airport since 2001.
