Fenwick Street in Northeast Washington remained closed Monday morning after a large part of a building in that area collapsed Sunday possibly because of strong winds.

On Monday, Metro said its buses in that area were running late because of the street closures in the Ivy City area.

No one was injured. Officials said about 400- to 500-square feet of a lower-level wall fell from a vacant building at Fenwick and Gallaudet streets. The building used to be a tomato-packing plant, D.C. fire officials said.

A minivan that was parked near the building was damaged in the incident.

Exactly what caused the building to collapse is still under investigation. Officials said high winds could have contributed.
