Brimbank Police have charged two teenagers following an alleged carjacking in Airport West and a crash in Keilor East this morning.
It is alleged a group of four teens approached a man along Louis Street in Airport West, threatened him with an axe and demanded his black Mercedes about 8.30am.
During the attack, the 25-year-old Forest Hill man sustained minor injuries and was treated at scene.
The offenders fled in the stolen Mercedes and a blue Holden Commodore, seen driving at excessive speeds of up to 160km/h on the Western Ring Road before crashing into a church on Ely Court in Keilor East about 8.40am.
Three of the teenagers dumped the Commodore and fled in the stolen Mercedes on Milleara Road.
The driver of the Mercedes then collided with a police vehicle along Woorite Place and the group were arrested at the scene.
An 18-year-old Reservoir woman, a 16-year-old Point Cook girl have been released pending further enquires.
A 14-year-old Ivanhoe boy and a 17-year-old Coburg boy have been armed robbery, aggravated carjacking and other driving offences.
They will appear at a Children's Court at a later date.
