Six people died in March when a cargo ship struck a pier of the Francis Scott Key Bridge in Baltimore, causing it to collapse.

BALTIMORE (CN) — The Justice Department on Wednesday sued the owner and operator of a container ship that crashed into the Francis Scott Key Bridge in March, killing six, seeking more than $100 million from the civil negligence charges.

Federal prosecutors on Wednesday filed suit against the owner of the container ship that crashed into the Francis Scott Key Bridge in Baltimore earlier this year, alleging that the company and those on board the ship knew about persistent faulty electrical and mechanical problems and failed to fix them.
