RCMP laid separate assault and criminal harassment charges following two disturbances in April.
Police responded to a complaint of assault at a Lowther Drive residence on April 27, according to a monthly report outlining activity in April that was provided to Cornwall council.
Following an investigation, one person was arrested and charges were laid.
Police received two other complaints of assault, which are still under investigation.
RCMP also arrested a person and laid charges following a complaint of criminal harassment at a John Street residence on April 24.
Two reports of break and enters are still under investigation by RCMP. Police responded to one of those complaints at a Hyde Street residence on April 9 and a Ferry Road residence on April 15.
RCMP also received a complaint of trespassing on a MacEwen Road property on April 15 but, following an investigation, there was insufficient evidence to identify a suspect.
Throughout the month, RCMP responded to five incidents under the Mental Health Act. As a result, one individual was transported to Queen Elizabeth Hospital for further assistance while four incidents were deemed as unfounded.
There were nine reports of theft under $5,000, with each associated with a string of vehicle break-ins. One individual has been arrested in connection with those, and charges have been laid.
The biggest theft in the month, over $5,000, was a complaint of a stolen car from a Meadow Bank Road residence. The vehicle was later located, but the matter is still under investigation.
Police also responded to 10 reports of mischief in April with two still under investigation. Eight have been resolved with no charges being laid.
