SWAT officers arrested a 37 year-old man at his Greenwood apartment today after receiving information from his out-of-state friend the Federal Bureau of Investigation (FBI) that he had made threats against a Seattle mosque.

Earlier today, the suspect posted threats online and, in a separate posting, claimed to have purchased an assault rifle and extra ammunition.

Acting on that information, SWAT and Hostage Negotiators went to the man’s home in the 11700 block of Greenwood Avenue North and arrested him shortly before 3:30 PM.

Investigators have learned the man has previously been contacted by area law enforcement who are investigating harassment and threats to another mosque.

Seattle police are working closely with the FBI to investigate the rapidly developing case.
