The FBI is conducting an underwater search for evidence in the Concord River in Billerica, Massachusetts, but they aren't saying what case the investigation is connected to.
The Underwater Search and Evidence Response Team, which is out of New York, is searching for "specific evidence," according to a news release from the FBI Boston Division. Local police are not involved with the search.
Although the release did not specify what is being investigated or what the evidence is, the FBI said they are not looking for human remains and there is no threat to public safety.
But there will be traffic disruptions, as the agency said one lane of the River Street Bridge will be closed during active search hours, which began at 9 a.m. Monday and could last all week.

At one point on Monday, the search crews were seen pulling up a yellow bag of what appeared to be some kind of evidence from the water. Investigators were also seen taking pictures in the area.
The entire neighborhood remains curious about what's going on right in their backyard.
"I love true crime anyway, so of course I'm like, 'Ooh,'" said Diane Stanley, who lives nearby.
She watched from her dock on River Street as crews started diving into the Concord River on Monday morning.
"We have no idea what they're looking for. We haven't been told anything," Stanley said. "I would just like to know what they are looking for and are we going to find out what it is?"
