The raid of a Baton Rouge, LA, home Monday and a pawn shop burglary last week are connected to the arrests of three people who said they were going to kill police at protests for Alton Sterling, reports WBRZ.

Three people - including at least one juvenile - have been arrested.

Monday, federal authorities raided a home in Old South Baton Rouge. A WBRZ news crew recorded video of agents with the Alcohol, Tobacco and Firearms; sheriff's deputies; and Baton Rouge Police going through the home. The homeowner said one weapon was removed from the home, and confirmed he was questioned by authorities. The person living there said he was letting someone live at the home for free and that person was gone when the home was raided Monday shortly after 5 p.m. A source close to the investigation said the person who was staying at the home was later arrested. The suspect's name was not immediately available.

The source, who asked not to be identified, said the authorities were working leads on a Government Street pawn shop burglary that happened after Sterling was shot and killed by police in Baton Rouge on Tuesday, July 5. Between seven and eight weapons were stolen, and one of the three people arrested after the raid told investigators during questioning that the guns and ammunition were stolen to be able to shoot and kill police during protests, of which there have been many recently in Baton Rouge.

The raid on the home Monday evening was part of a federal search warrant, WBRZ learned.

Sources told WBRZ that at least three weapons have been recovered.
