He has to be home by 9pm and he can't got to his local shops alone.
But he says it's unfair because no one else in his gang has one:
"Every time something was going wrong at the shops people would walk past, not look at the culprit, and look at me - and ring the police on me.
"I was the only person out of about 12 kids that got put on the ASBO."
Liam's dad said he's being picked on unfairly. And many of their neighbours agree with them.
The group of charities - Shape - want to look carefully at the reasons why kids get in trouble and if there are better ways to help them.
