Four teenagers arrested after allegedly robbing man, stealing 4WD, stopping for Maccas and crashing into tree in Sydney's south The scene of the crash at Como. A BIZARRE and near-fatal chain of events culminated this morning with police arresting four teenagers after they allegedly crashed a stolen four wheel drive in Sydney's south - coming within inches of careening off a sheer cliff and onto the train tracks below. But not before stopping for a quick takeaway at a 24-hour McDonald's following an alleged robbery of a man of his phone while on a train. Ttwo of the alleged offenders - including a teenage girl - were left under police guard at St George hospital while the other two remained at Sutherland police station waiting to be charged. Their alleged crime spree began shortly before 1am when the juveniles approached a man on a train between Engadine and Sutherland stations and produced a liquor bottle. "They threatened the passenger with the bottle and demanded his mobile phone," Miranda police Inspector Steve Egbers told The Daily Telegraph. The man handed his mobile phone over and the offenders got off the train at Sutherland and ran. Once off the train, the four teenagers found a green Mitsubishi Pajero and headed northeast in the vehicle. Unbelievably, the young bandits then found time to make a stop at a nearby McDonald's - believed to be Kirrawee - before continuing down the Princes Highway. Staff at the fast food outlet this morning said they could not remember any customers fitting the groups' description. Following their early morning feed the four young friends made their way to the hilly and dimly lit streets of Como. "They aren't from around the area, they were driving all over the place like they were lost," said Insp Egbers. The teens ended up on Como Parade - a windy and steep street running parallel to the Illawarra train line. There, they lost control of the vehicle, mounting a curb and dropping at least three metres off an embankment, through a metal fence and into a tree on the edge of the cliff. "They're lucky, a few metres to the right and they'd be dead," said a Sutherland police officer at the scene this morning. Police inspect the scene of the crash at Como. The rail line is straight below us ... it's a sheer drop. The female suffered facial lacerations and soft tissue injuries in the crash, while one of the males suffered soft tissue injuries "consistent with a high impact injury." After the car came to an incredibly lucky stop, the teens allegedly sprinted north on Como Parade towards the local train station. On the way down the hill, one of the foursome called 000. "On my way to the crash scene I saw an ambulance heading in the same direction," said Insp Egbers. I thought 'I bet one of the offenders has called an ambulance' Sure enough, the paramedics knew more than we did - they told us they were heading across a bridge at the train station. That's when I got two officers to wait on the other side of the tracks with a net and say: 'Thanks for coming'. We arrested them on the other side of the tracks, it was really, really good work all around. The teenagers - two of whom are aged 16 and 17 - will be charged with a number of offences later today. Police found an empty purse belonging to the vehicle's owner nearby, while the stolen phone is yet to be recovered.
