Updating another crime story. Investigators have also made an arrest in the case involving a number of suspicious packages that were addressed to more than a dozen prominent U.S. Democrats and critics of President Trump. Some of the packages carried pipe bombs, though none of them went off.

A break in the case came last Thursday, when investigators traced five of the packages to a mail processing center near Miami, Florida. Then, they found a fingerprint on one of the bombs, and that led them to the suspect.

The FBI says the manhunt for the person responsible has ended, but police say Americans still need to be cautious because there could still be some packages in the mail. The FBI hasn't said yet what they think motivated the suspect. His van was covered with pictures of politicians, and some of the Democrats had target signs on them.

The suspect reportedly told investigators the bombs weren't designed to actually harm anyone. But the FBI says they were not fakes. Police believe he was making the packages inside his van where officials found stamps, envelopes and other mailing equipment.
