A man was arrested after he slashed a man on his neck with a knife while boarding a Greyhound bus late Monday night.
Officers responded to the 200 block of S. Lamar St when witnesses say a 20 year old man was seen talking to himself while boarding a bus making statements about people being out to get him.
He then pulled a box cutter out of his pocket and slashed the person in front of him on the neck.
Security guards tackled the man and detained him until Dallas police arrived to the scene.
The victim was taken to a nearby hospital in stable condition.
The suspect was arrested and taken into custody and charged with aggravated assault with a deadly weapon.
