The odd incident started with a 25-year-old Northern Territory man and a 23-year-old woman hiring a taxi to Dry Creek at around 7.45 in the morning.

Police claims when they reached the destination they demanded the driver to leave the car so they could have sex in the backseat.

Then they ordered the driver to get in the passenger seat and drove him to North Adelaide.

Once there, the taxi driver took the opportunity to call for help.

The couple then allegedly attacked the driver, punching him in the head and hitting him with a high-heel shoe, after refusing to pay the 72-Aus dollar fare.

However, cops managed to track them down, reports News.com.au.
