Police are investigating two burglaries in the same Pentwyn steet.
The South Wales force today issued an appeal for anybody who may have seen anyone in or near Hollybush Road carrying a large suitcase on the afternoon of Friday October 19.
A television and a large navy blue suitcase were stolen from one house, while a laptop computer was taken from another.
It is thought the burglar used the suitcase to transport the stolen items.
Anyone who saw anything suspicious in the area, or who has any other information, is asked to contact DC James Morris on 07584 004107 or Crimestoppers anonymously on 0800 555 111.
