POLICE are investigating after a safety fence which borders a major highway was damaged twice in as many nights.

A group of four juveniles on pushbikes is believed to have damaged several fence panels on Friday and Saturday nights.

Roma Senior Constable Mick Hewitt said eight panels of the fence along Apex Park, which borders the Carnarvon Highway, were damaged overnight Friday.

Maranoa Regional Council and Apex Park workers fixed the fence on Saturday morning before the group returned and damaged it again.

Snr Constable Hewitt said five panels were damaged in the second instance.

"(The fence) is to stop children running out onto the highway," he said.

"It's a part used by families and travellers to have a rest.

"There's quite a lot of traffic along that highway.

"There's not a lot of crime out in Roma so for this to happen two nights in a row is just very cheeky."

The park is located on the northern end of town.

Initial investigations had suggested a group of about four juveniles riding pushbikes could be responsible.

Investigations are continuing, and anyone with information is urged to phone Crime Stoppers on 1800 333 000.
