RYAN Webley's LSD experiment went horribly wrong.
On November 25, the 20-year-old broke into the West Rockhampton home of a woman, in her late 60s, and attacked her, pushing her in the face and standing on her ankle.
On Friday, Webley appeared in the Rockhampton Magistrates Court where he pleaded guilty to four charges, including counts of serious assault of a person aged over 60, burglary and wilful damage.
His defence lawyer told Magistrate Mark Morrow, Webley had been experimenting with drugs and taken two LSD tablets before the incident.
The drugs had an immediate reaction.
Earlier in proceedings, prosecutor Gavin Reece said Webley had accessed the home through a back screen door.
Mr Reece said the woman was in her bedroom when she heard Webley enter.
He said the resident went to investigate a noise, startling Webley.
Mr Reece said Webley then pushed the woman in the face and as he moved towards her stood on her left ankle, causing significant pain for the victim.
He said the woman called out to her daughter who was in another room and Webley ran off.
Police were called and a short time later found Webley a couple of streets away.
Mr Reece said as police went to transport him to the station, he kicked out the rear window in the vehicle and reached out and grabbed an officer by the shoulders.
He said officers were forced to use capsicum spray to restrain Webley.
The court heard Webley declined to be interviewed when officers got him to the station.
Webley had no prior criminal history.
Webley's defence lawyer said his client had been raised in a loving, family home.
He said Webley's behaviour was drug related.
"Drugs are proficient within youth in our community," the lawyer said.
"He took two tablets and had an immediate reaction.
"Of course, consumption of drugs is no excuse for what he did."
However, the lawyer said it pointed to the capacity for Webley's rehabilitation.
Magistrate Mark Morrow warned Webley about drugs.
"This is a very serious offence, this woman lives in her own home and you came in and pushed her over," Mr Morrow said.
He placed Webley on 15 months probation, which includes regular drug testing, and ordered he complete 100 hours of community service.
