Police are investigating a series of break-ins across South Hedland during the red alert for Cyclone Veronica at the weekend.

McDonald’s manager Luke Jessop said CCTV footage showed his store was broken into a number of times over the weekend, with thieves allegedly stealing money from the Ronald McDonald House charity collection.

Those involved had also tried to break into the manager’s office.

It is understood a number of other South Hedland stores were raided over the weekend.

A spokesman for WA Police said local officers were investigating four commercial burglaries in the area from the weekend.

He said one group predominantly made up of juveniles under 10 years of age is suspected to have been involved.

“Inquiries are also continuing in regard to the welfare and parenting of the children involved in this series of burglaries,” he said.

“Inquiries are continuing to establish if any other businesses were targeted.”

He said there were a “small number” of burglaries at other commercial premises across the Pilbara during the Red Alert phase of Cyclone Veronica.

He said alcohol appeared to be the motivation behind these offences.

“Aside from the small number of incidents that appear to be linked to this one group of people, there is no evidence of broader public order or crime issues over the weekend,” he said.

When red alerts are issued people are warned to stay indoors until the all clear is given by authorities.

However, a shocked Joanne McDonnell caught video footage of children riding their bikes and skateboards through the windy and wet streets of Port Hedland while the red alert was current.
