Police are investigating a report of suspicious behaviour in Mount Gambier last week.

About 4pm on Thursday two children were walking on Lake Terrace East when a man sitting in a white sedan allegedly beckoned the children towards him.

The two girls did not approach the man and there was no conversation.

The children left the area and reported it to parents immediately.

The white sedan, possibly a Mitsubishi Magna or similar, had a distinctive piece of cardboard covering the rear left passenger window.

There is no further description of the man.

Police searched the area but were unable to locate any cars matching the description.

A police spokesperson said Thursday’s incident was not believed to be linked to a suspicious behaviour report earlier this month near Mulga Street Primary School.

Anyone with information that may assist is asked to contact Crime Stoppers online at www.crimestopperssa.com.au or by phoning 1800 333 000.
