Vadbhaj Singh, 24, said he picked up the pair on the corner of Bourke and Exhibition Street in the CBD about 4am on Friday, July 24.
Mr Singh said before they got into his taxi, which wasn’t fitted with a protective barrier, the men refused a lift from another cab that had a shield.
After prepaying $20 for the ride, the two men directed Mr Singh to Hollick Street, Richmond.
As one of the offenders stepped out of the car, the other produced scissors and began stabbing at Mr Singh while demanding cash and the car’s GPS device.
“(The attack) appears rather frenzied,” said Victoria Police detective senior constable Dean Higgins.
“He’s kept attacking the driver while he’s been driving.”
“The footage shows the driver putting his hands up to protect himself, but the male at that stage doesn’t seem too concerned.
“He then tried to put a finger in [Mr Singh’s] mouth … to stop him from driving.”
Mr Singh’s said his reaction was to start driving toward safety.
“I really wanted to drive to the police station,” he told reporters today.
“I wanted to get onto a busier road because that was a really quiet street, so maybe some others taxi drivers who were passing, maybe they will stop and they will assist me,” Mr Singh said.
“They knew the area very well so that’s why they took me there.
“That was a dead end street which ends with a laneway.”
In an attempt to stop the attack, Mr Singh returned the scissor-wielding man’s $20, but he threw it back into the cab before fleeing without any cash or the GPS.
Police described the robbers as of caucasian appearance, aged in their early to mid-20s.
One was wearing a light coloured button-up shirt, while the other wore a dark-coloured top.
