A man was taken into custody in the search for a man who school police said walked inside a Boston University building and displayed a knife before fleeing.
The man brandished a knife inside 1010 Commonwealth Avenue, which houses the university's Metropolitan College & Extended Education programs, according to police.
The man then fled and boarded an MBTA Green Line train toward Boston. Transit police and Brookline police joined the search, according to the Boston University Police Department.
They said in an update later Wednesday that a person was taken into custody and thanked members of the community for helping in the search. They didn't identify the person or say how they were tracked down.
