Mayuran Lingathas, 23, denied he was drink driving when police arrived at the scene at 12.12am on July 13.

According to police facts, Lingathas had been drinking on July 12 and at about 11.50pm he drove a silver Mercedes-Benz four-wheel-drive from the university to a petrol station on the Northern Distributor Road and back.

He was reported to be driving all over the road at high speed on Leeds Parade and hit a median strip and no through road sign at the first entry to the university. The sign came off, the pole bent, one of the vehicles front tyres exploded and sheared off the rim, and a side mirror was broken off.

A university security guard witnessed the crash and phoned police who arrived at the scene and saw the vehicle with its brake lights on, Lingathas was in the drivers seat and another man was behind vehicle.

Lingathas told police the car had been there since 6pm and denied driving it, saying he had come back to get it towed. However the passenger said they had gone to a petrol station to get cigarettes and the security guard also spoke to police.

After failing a breath test, Lingathas was arrested and taken to Orange Police Station for a breath analysis and a blood sample. He had earlier said he didnt have his drivers licence on him, he refused to answer questions, and police said he was belligerent.

On Monday, solicitor Andrew Rolfe said Lingathas pleaded guilty and along with being under the influence of alcohol he also took prescribed medication and had no proper memory of the incident.

Magistrate David Day fined him $1650, disqualified him from driving for six months, back-dated to July 13, and ordered him to have an interlock device fitted to his vehicle for 24 months. Lingathas was also convicted and fined $220 for not giving his details to police.
