On Monday, federal agents boarded the Dali, the cargo ship that decimated Baltimore's Francis Scott Key Bridge, as part of a criminal probe into whether the ship's crew was aware that the vessel had technical issues before they set sail, according to a report. 

Several indivduals boarded the ship, in two groups, shortly after sunrise, the Washington Post reported. The Federal Bureau of Investigations confirmed that its agents were among the individuals seen in the harbor.

"The FBI is present aboard the cargo ship Dali conducting court authorized law enforcement activity," the agency told the Washington Post.

The 985-foot ship lost power, while leaving the Port of Baltimore, on March 26. The ship rammed into a support pillar on the Key Bridge, while an eight-member construction crew was working to repair the structure. Six of the individuals on the bridge, at the time, fell into the water and died.

Officials are now investigating whether the ship's crew was aware of the potential techical issues before they left the port, the Washington Post reported. In addition to the criminal investigation, the National Transportation Safety Board has also launched a probe, intended to assess what caused the crash.
