Many of the parents were shocked to learn that their children had been drunk or on drugs, climbing up scaffolding or throwing stones at strangers in the street.
The States police set up the initiative to encourage parents to take more responsibility for their child’s whereabouts late at night.
So far, 117 letters have been sent out by the force’s youth affairs officer.
Most of the letters warn parents that anti-social behaviour is the main cause of distress to members of the community, and inform them of their child’s behaviour while drunk or on drugs.
P insp Mary Le Hegarat said that the campaign was working well.
‘In some cases we have had parents contacting us saying that they have been shocked to receive a letter from the police about their child,’ she said.
‘They have told us that it has really alerted them to what their child could be doing.’
