TMZ Sports has learned Terrell Suggs' arrest on Tuesday stemmed from a March incident in which he allegedly brandished a gun and threatened to kill a man during an argument at a Scottsdale, Arizona Starbucks.
According to court documents we obtained, the altercation happened at a drive-through at the coffee joint at around 12:28 PM on March 10.
In the docs, officials say Suggs had driven past the ordering speaker ... and when he put his Range Rover in reverse to remedy the situation, he made contact with another man's vehicle.
