A group of teenagers who allegedly left three highway patrol officers injured during a random breath test in Sydney's west are due to face court.
One senior constable suffered a broken nose while the other two patrol officers have sprained wrists or hands.
The officers were conducting an RBT in Blacktown early on Thursday morning when one of them issued a 17-year-old P-plate driver with infringements notices for exceeding his passenger restrictions, police say.
It's alleged the teenage boy threw the notices away before assaulting the officer.
Two other teenagers in his car joined in on the attack, and also assaulted two constables who came to help, police said.
