Police are warning motorists after a spate of car break-ins in Grangetown.
Residents are also being warned to keep a look-out for youths on bikes who have been targeting valuables in cars.
The group, usually dressed in hoodies, have been known to target vehicles with valuables on display or left unsecured.
PCSO Hannah Campbell-Todd told Grangetown PACT meeting that the thieves operated “very, very quickly” and warned drivers not to leave their vehicles unlocked for an instant – while also making sure valuables were not left behind when cars were locked.
A van driver left the window of his white van open in Mardy Street and a wallet was stolen.
Vehicles have also been targeted on Havelock Place and on Thomas Street and Bishop Streets.
Two cars were also broken into overnight on Tuesday.
If you see a group or individual acting suspiciously around cars call 999 for an immediate response.
The PACT meeting has agreed to make drug dealing in the north Grangetown and Pentre Gardens areas a continued priority. Since the last meeting, there had been an arrest for a drugs offence and drugs recovered after a routine stopping of a car. A cannabis factory was also neutralised in Pentre Gardens although suspects are still being sought.
There had also been five warrants issued for prostitution offences.
Residents also complained of continued issues with litter and fly-tipping. Ashley Lister, secretary of Grangetown Community Action, said there had been a positive meeting with the new waste enforcement officer for the area, who had already been involved in enforcement action at addresses where waste was being left out on the wrong days.
Meanwhile, police have asked cyclists to make sure their bikes are secured after 20 thefts in Grangetown and Butetown in recent weeks. The next monthly PACT meeting is being held at Channel View, 7pm on Wednesday 6th July.
