"We'd be happy to send them out with our graffiti removal team,'' she said.

"A lot of the community would like them to clean it up.''

The invitation arose after police arrested a boy, 17, from Kirrawee, on September 24 as a result of a tip-off from residents.

They reported a youth spray-painting graffiti on rail noise barriers between Sutherland and Kirrawee stations at 5pm.

Sutherland officers found a teenager in a car with spray cans but later released him.

He returned to Sutherland police station at 11.30pm with his mother and admitted his role in the graffiti attack.

Police gave him a caution for malicious damage, possessing spray-paint cans and entering railway land.

Cr Kelly said she was pleased to see that he had taken responsibility for his actions but said police should have the ability to order vandals to remove their marks.

"The State Government needs to look at the Young Offenders Act,'' she said.

"There should be more moves and more options to make offenders clean up their graffiti.''

Should vandals be forced to clean up their own graffiti?
