A MOTHER has described her teenage son as a pathological liar in Grafton Local Court where a police constable went on trial facing two charges of common assault yesterday.
The alleged assaults against minors occurred in two different incidents.
The first is alleged to have occurred in November 2010 outside Grafton High School involving a young man who was not a student at the school.
The second incident is alleged to have occurred in an interview room of a department store after a 12-year old boy was caught with stolen goods in April last year.
The Director of Public Prosecutions alleged Constable Stephen Bell used excessive force during an interview with the boy, lifting him out of a chair and throwing him at a wall, then pushing his head into the wall.
The allegations were denied by Const Bell.
The claimant gave evidence to the court via a video link.
The boy told the court he was "thrown" against a wall head first and was also hurt when his head was pushed back against the wall for a second time by Const Bell.
The boy, who could not be named for legal reasons, said he had a sore head after the incident and suffered a headache for three days.
His mother testified later in the day her son was a "pathological liar," and it was "a load of crap" he had a headache after the incident.
Const George Chakty, Const Bell's partner on the day, reported the incident to a superior about three months after it occurred.
The way the young man was placed against the wall had been "eating away at me", he said.
Const Bell used more force than he needed to, but he did not slam the boy against the wall, Const Chakty testified.
The court also heard from a security guard, Todd Reeves, who witnessed the event.
He said Const Bell did not slam or ram the boy, nor did he push his head into the wall.
The trial was adjourned to November 2.
