A police forensics team had inspected the site, and it appeared the perpetrators had used disposable gloves, with one left at the scene.
An older model computer, which had been brought in to replace the one stolen in the previous burglary, had not been taken, and staff were still trying to ascertain if anything was missing.
Ms Curtis said the break-in was extremely disheartening for the team who worked at the store, all of whom felt extremely sad that people could have such disregard for the work the charity does.
She said they would be investigating extra security, including installation of cameras and sensors. She also asked for anyone who may have heard or seen anything to contact the police.
The best way the community could support the charity, she said, was to keep shopping at the store, and continue to donate clean, saleable used goods.
