BBC
The FBI has opened a criminal investigation into the Baltimore bridge collapse, sources familiar with the matter told the BBC's US partner CBS.
The investigation will examine the circumstances leading up to the incident, in which six people were killed.
The Francis Scott Key Bridge fell on March 26 after it was struck by a large container ship called the Dali.
Federal agents have been present at the site since, the sources said.
In a statement on Monday, a spokesperson for the Department of Justice (DoJ) said the "FBI is present aboard the cargo ship Dali conducting court authorized law enforcement activity".
