The Boston Police Department announced that it has taken into custody three new suspects as a result of its ongoing investigation into the Boston Marathon bombing.

As you can see from the BPD’s tweet, details are scarce at this point. They quickly followed that up with another tweet saying that “there is no threat to the public,” so it seems safe to assume there aren’t any other bombs out there waiting to be discovered.

The investigation continues, with surviving bomber Dzhokar Tsarnaev currently being held in a prison medical center. He has been charged with using a weapon of mass destruction. His brother, Tamerlan, was killed in a shootout with police on April 19.
