A 29-YEAR-OLD man left a nasty surprise in the Rockhampton watch house last month.

Police officers had to call in the cleaners after Justin Peter Raaen defecated on the floor of his cell.

Raaen pleaded guilty in the Rockhampton Magistrates Court yesterday to wilful damage and contravening a direction on June 22.

Police prosecutor Acting Senior Constable Manon Barwick told the court the defendant was arrested about 1am for failing to move on from the CBD night club precinct.

Act Snr Const Barwick said Raaen was taken to the watch house and placed in a cell with toilet access.

However, he was moved to a padded cell after he started hitting his head against the wall.

The court heard Raaen did his business on the ground and made rude gestures afterwards.

Magistrate Bronwyn Springer said this suggested Raaen was not very remorseful.

Act Snr Const Barwick said at no time did Raaen advise staff he needed to use the toilet.

The court heard Raaen had a criminal history, mainly related to drug offences.

He was on a suspended sentence for an assault at the time of this latest offending.

However, Ms Springer chose not to activate this.

She placed Raaen on a nine month probation order and fined him $350.
