The FBI has opened a criminal investigation into the Francis Scott Key Bridge collapse in Baltimore, a federal source confirmed to Fox News.

The probe, first reported by the Washington Post, centers on the 985-foot container ship, the Dali, looking at any violations of federal maritime law, with a focus on whether ship personnel may have been aware of any onboard technical or operational issues before the ship left the Port of Baltimore, according the source with knowledge of the ongoing investigation.

Authorities are looking into the events leading up to the moment the ship lost power before slamming into one of the bridge’s support pillars, the Post reported, citing two U.S. officials familiar with the matter.

In a statement to Fox News Digital, the FBI confirmed the bureau "is present aboard the cargo ship Dali conducting court-authorized law enforcement activity."

"My office generally will not confirm the existence of or otherwise comment about investigations," Erek L. Barron, the U.S. Attorney for Maryland, said in a statement to the Post. "However, the public should know, whether it’s gun violence, civil rights abuse, financial fraud, or any other threat to public safety or property, we will seek accountability for anyone who may be responsible."
