NEWPORT, R.I. (AP) — Authorities in Rhode Island say the man who gunned down 12 people at the Washington Navy Yard called police last month to complain that voices were harassing him through the walls of his hotel room and he worried they might harm him.

Newport police say they were called to a Marriott around 6 a.m. Aug. 7. Aaron Alexis told them he was in town as a naval contractor. Newport is home to a naval station.

According to a police report, Alexis says he got into an argument while boarding his flight in Virginia and the person he argued with sent three people to follow him and keep him awake.

Police Lt. William Fitzgerald says police alerted security at the naval station. A spokesman for the station did not immediately return a call seeking comment.
