DUNDALK, Md. (AP) — A two-alarm fire has heavily damaged a Baltimore County crab house that is a landmark in the Dundalk neighborhood.

Lt. Jay Ringgold of the Baltimore County Fire Department says an employee of Ross’ Crab House noticed a fire in the restaurant’s basement at about 7:25 p.m. Sunday. The spokesman said six employees and 15 customers who were in the house-like structure were safely evacuated, and a fire engine that was a block away was on the scene a minute later.
