The man charged over the incident, Anthony Slater, allegedly drove the taxi dangerously around the Ballarat CBD - including outside the Dana Street police station.

Slater fronted the Ballarat Magistrates Court on Tuesday where he did not apply for bail over the carjacking terror, which started at 9.10am on April 19.

According to a police summary obtained by The Courier, a man made a booking with Ballarat Taxis and the driver collected the accused, who sat in the front passenger seat.

During the taxi trip, the accused was allegedly becoming increasingly agitated and told the driver to speed and drive through a red light.

"The accused has pushed the victim with his right hand to the shoulder. The accused was holding the syringe in his left hand and told the victim to get out," the summary reads.

"The accused had become much more aggressive, he continued to push at the victim and thrusting the syringe toward his throat.

"The victim, terrified, brought the vehicle to a complete stop and exited the vehicle."

Police say the accused got into the driver's seat and drove at fast speeds, tailgated a car and drove on the wrong side of Dana Street.

"The accused continues to drive around Ballarat while committing a litany of traffic offences for the next 15 minutes, driving on the wrong side of the road on numerous occasions, crashing multiple red lights, side-swiping a caravan and hitting a concrete bollard," the summary states.

Police allegedly detected the accused doing a burnout while travelling around the roundabout in front of the Ballarat Police Station.

He then allegedly tried to park the taxi but when he exited, it rolled forward into a parked car.

The police summary says the accused entered the police station foyer where he was arrested.

"The accused presented as being heavily drug affected, paranoid, irrational and as such was not interviewed," police say.

Slater's lawyer, Manny Brennan, told the court his client had an intellectual disability, needed to see a psychiatrist and was taking prescribed medication.

Magistrate Barry Schultz made notes of Slater's custody management issues, and remanded him in custody.

Wearing track pants, a jumper and socks, Slater looked worried while sitting in the dock for the brief filing hearing.

Slater faces six charges over the April 19 incident, including aggravated carjacking while on bail, assault, car theft and robbery.

He has been charged with stealing a $300 spanner set from Sebastopol's Mesh and Masonry on April 6.

A committal mention was set for July.
