MILWAUKEE (AP) — Three people have been arrested in connection with the theft of a multi-million dollar Stradivarius violin stolen from the Milwaukee Symphony Orchestra concertmaster. Assistant District Attorney Kent Lovern said Wednesday he couldn't reveal any information beyond the arrests. He says he doesn't expect a charging decision to be made before Thursday. Police say the nearly 300-year-old violin was on loan to concertmaster Frank Almond. Authorities say a robber used a stun gun on Almond and took the instrument from him in a parking lot of Wisconsin Lutheran College, where he had just performed Jan. 27. The violin has been appraised at $5 million. The Milwaukee Symphony Orchestra says someone recently offered $100,000 for the safe return of the violin.
