Part of the ceiling collapsed at the Borough Hall subway station in Brooklyn this afternoon.

The incident happened around 3:30 p.m. Wednesday. Witness Eric Chan wrote on Twitter that he heard a loud bang, then saw the collapsed ceiling at the front end of the Manhattan-bound 4/5 train platform. A police spokesperson says that there was one minor injury in the partial collapse.

@NYCTSubway I heard a loud bang, I turn around, and a part of the ceiling COLLAPSED. This was on the Manhattan bound 4/5 train platform near the front end. There was a lady standing close to the platform edge and her suitcase got knocked over from the debris, I hope she’s okay. pic.twitter.com/7vRzi8SabZ — Eric Chan (@Erikku_Chan) June 20, 2018

Roof caved in at #BoroughHall. Police say one person was injured. 4/5 trains bypassing the stop. Hey @NYGovCuomo can you fix the subway so we don't have to worry about the roof falling in? #nyc #subway cc: @CynthiaNixon pic.twitter.com/H3KA1tNqFT — Andrew Welch (@andrewpwelch) June 20, 2018
