A 59-year-old Baltimore man was arrested Wednesday after police said he called 911 and said he was from Boston and was going to "blow some more stuff up."
According to Anne Arundel County police, Ronald William Smith made the threat about 12:40 p.m., and then hung up.
Authorities said they were able to trace multiple calls from the same number to a residence at 1305 Broadview Drive in Ferndale, Md.
Smith admitted to make the calls but said he did not really plan to set off any bombs.
Smith was arrested and charged with making a false statement about a destructive device, misuse of telephone and arson threats.
Police checked the Ferndale home and Smith's residence on South Calhoun Street in Baltimore and did not find any explosives materials.
