The incident was reported to police around 5 p.m. Wednesday, and police went to the business to check out the message.
The business had its information technology person working to purge the server of the hacker’s software. Ouellette suggested that if residents receive a similar threat, police should view the computer first to see if there is any evidence they can use before contacting a technician to fix the problem.
Other than hacking into the computer, the hackers did not cause any monetary damage, nor were they able to steal any files, Ouellette said.
