A Dubbo motorcyclist who was giving his son a lift home from the pub was one of 10 witnesses to give evidence on the second day of a hearing involving two Dubbo men accused of assaulting a NSW Corrective Services officer in September last year.

Ryan Leigh Maas and Steven John Madden have been charged over the incident on the night of September 23, that resulted in the alleged victim, Michael Weeks, being taken to hospital.

Maas has pleaded guilty to the charge of failing to quit the premises when refused entry by licensee, and both men have pleaded not guilty to the other charges.

Those charges are maliciously inflicting grievous bodily harm, inflicting actual bodily harm and affray.

Eight police officers from Dubbo including one from Forbes and a passing motorist also took the stand at Dubbo courthouse yesterday.

David Walters, 58, picked up his son on his motorbike from the Commercial Hotel in the early hours of September 23 when he came across a man lying on the road at the intersection of Talbragar and Darling streets.

“We stopped and thought we had better get this guy off the road,” Mr Walters said.

Mr Walters told the court that a couple of people had turned up and asked what happened, to which Mr Walters responded,

“I think this guy has been beaten up”.

Next to give evidence was Sally Anne Roberts of Dubbo, who at 2am stopped at the intersection of Darling and Talbragar streets and saw a man on side of the road.

She also observed three men running across the road from Thrifty Link to Victoria Park.

Mrs Roberts told the court “the man was badly bashed and had a ripped shirt and a graze on his left shoulder,” she said.

In giving evidence Senior Constable Nicholas Kosseris - who was second-in-charge of the matter - told the court a bloodstain was located outside Thrifty, the area where Maas had allegedly ran from the scene.
