Qld police appeal for arson attack info

Queensland police are urging people with dash-cam footage from the Logan area to come forward to help solve an arson attack on a family home.

A 33-year-old woman and six children were inside the Douglas St house on Sunday night when two objects were thrown through the windows, causing small fires.

A third was started in the external carport.

Detective Inspector Mark White said police had no suspects and little information about whether it was a random or targeted attack.

Insp White said there was "no doubt" people were withholding information and he urged them to come forward.

"Someone out there will know something," he said on Tuesday.

It was the fourth time in recent weeks the property had been targeted.

There was another fire two weeks ago and two separate graffiti attacks.

The most recent vandalism occurred in the days leading up to Sunday's fire, where the words "FU YOR DEAD" were spray painted on the front of the property.
