A hacker armed with radio codes set off emergency sirens in Brunswick early Wednesday. If the blasts didn't wake the city's 35,000 residents, follow-up phone calls to residences probably did the trick.
Police were unable to override the hacker's radio tones and had to turn off each of the six sirens by hand. The noise, which began at 12:44 a.m., went on for about 20 minutes.
The battery-operated devices were turned on twice March 27, prompting more than 1,000 calls to police after 1 a.m. The barrage of calls knocked out the department's phone system.
In response to the March incidents, a notification system called CodeRED was installed in city offices. It was used Wednesday morning to call 13,000 Brunswick telephones to inform residents that the blaring sirens were not signaling an emergency.
It was the second night this year the sirens were illegally activated.
