Police patrols have been stepped up again following anti-social behaviour in Barry.
There have been at least 12 reported incidents of eggs and stones being thrown at cars and homes in and around Victoria Park Road over the last four weeks.
Officers are warning youths that such behaviour will not be tolerated and ''appropriate action will be taken''.
CCTV footage is being monitored and local shops are being notified.
PC Helen Kihlberg, from Barry police station, said: ''This has been causing considerable distress to the residents who not only have the cost but also inconvenience of clearing up the mess and repairing any damage.''
''We have been providing an increased visible presence to reassure residents and act as a deterrent to those responsible.''
''I am pleased to say that we have had some positive feedback from residents who say they have noticed a difference, but our patrols will continue.''
South Wales Police said it was working with the parks department at Vale of Glamorgan Council to try and identify those responsible.
The patrols follow a similar response in the Holton Road area last month, where at least ten youths were reported for ''making a nuisance of themselves'' by littering, thowing drink cartons and swearing.
If you have any information about anti-social behaviour in Victoria Park Road, contact South Wales Police on 101, or in an emergency, call 999.
