Police have arrested an 18-year-old man after a police officer and elderly woman were injured in Victoria's east this morning.
The teenager was arrested at a pine plantation after fleeing from police on Traralgon West Road just before 7.30am.
The arrest follows a home invasion at a residence on Wallace Court about 2.50am this morning.
It's alleged the teen and a second offender woke the female occupant and assaulted her before stealing her bank card and fleeing in her Mazda 3.
The two offenders were spotted with the Mazda 3 by police at a service station on Moore Street, Moe about 6.10am.
Officers attempted to block-in the vehicle before the offending driver allegedly intentionally drove at police and subsequently ran over an officer's foot.
During the course of the incident, a police officer discharged his firearm before the vehicle fled the scene.
The male detective Senior constable sustained an injury to his foot and was taken to hospital.
The 78-year-old Traralgon woman assaulted during the aggravated home invasion was taken to hospital with non-life-threatening injuries.
The arrested teen, who was not injured, is expected to be interviewed by detectives.
The second offender remains outstanding and investigations are ongoing.
As per standard procedure, Professional Standards Command will oversee the investigation due to a police firearm being discharged.
