Chatham-Kent police are concerned about the high volume of 911 hang up calls received over the last day. 21 to be exact. They would like to remind everyone that if you dial 911 by mistake to stay on the line and clear up the mistake. Otherwise dispatchers will assume there is a problem and send help. Since these calls use up considerable resources police are asking you to “lock it before you pocket” your cell phone. For non emergency calls you can reach the front desk of Headquarters at 519-352-1234.
