The Children's Court heard the boy, 16, and a man stole the kitchen, which had not yet been installed, from a property in Wiegards Road, Lockwood, overnight on October 11.

The police prosecutor said they also stole two basins, bench tops and bathroom vanity units.

The property was loaded on a trailer and driven to a third man's address, the court was told.

The same evening, the pair went to an adjoining property in Wiegards Road, intending to steal two water tanks, but they contained water and could not be moved.

The court heard they then went to another house under construction, in Sunrise Drive, Lockwood, and stole two door frames and a door.

The prosecutor said the pair later returned to the address and loaded a 25,000-litre water tank on to the trailer.

In a police interview, the teenager made further admissions that two weeks before, he and the man went to an Inglewood address where a house was under construction and stole two gas cylinders.

"Investigations revealed the cylinders were stolen from the new doctor's residence being built at Inglewood Hospital," the police prosecutor said.

All property, except the vanity basins, was recovered.

The boy's defence lawyer said that within the space of three weeks, the boy had been involved in some significant offending.

She said the teenager, who has autism, effectively went along and did what he was told.

"In no way is it suggested that the defendant was the principal offender, that he was the brains of the operation," she said.

The matter was adjourned until early February so a pre-sentence report could be prepared.
