Two female police officers were kicked in the head and body during a brutal attack in Melbourne's north.
A brother and sister are accused of launching the alleged attack at South Morang, leaving two female officers injured in hospital.
Just before midnight on Saturday a BMW was seen driving erratically in Mill Park, police allege.
After a short pursuit the vehicle stopped at a house at nearby South Morang, missing a wheel.
Yak Dut, 21, and his sister allegedly got out of the vehicle, before a fight with the two officers broke out.
Police allege Dut kicked both officers while his sister punched at least one of them in the head.

Seven News understands the officers were forced to use capsicum spray to gain control of the accused.
The assault left the officers aged 36 and 57, both hurt, bleeding, bruised and swollen.
The 36-year-old officer had ligaments torn in her neck and a suspected torn bicep from a hard kick to the shoulder.
Dut is facing 24 charges, including: threats to kill, assaulting a police officer, kicking a police officer, reckless conducting, endangering life and drink driving.
He didn't apply for bail at the Heidelberg Magistrates Court on Wednesday.
Despite serious charges, his sister was however granted bail to appear in court at a later date.
