Thieves have bashed residents during a Pilbara home invasion and rammed into a police vehicle as they fled in a stolen 4WD.
A man received facial injuries in the attack and two police officers were hospitalised after attending the break-in at the house in the Karratha suburb of Nickol at about 2.45am.
Two men forced their way into the Windgrass Way home and assaulted a man and a woman before stealing their Toyota Landcruiser.
Police, who were called to the property, blocked the road with their police vehicle in an attempt to stop the thieves from driving away but were rammed by the 4WD several times.
The police vehicle was pushed about three metres across the road before the thieves drove away in the 4WD.
One of the officers received leg injuries and the other was injured in his neck and back after the crash.
Another woman who was inside the home has also been treated for minor injuries.
Anyone with information on the incident or the car, which has the registration number 1AKS523, is asked to contact Crime Stoppers on 1800 333 000.
