The investigation into last month's knifepoint robbery at Victoria Ave McDonald's continues, and forensic testing is under way.
Just before 4am on June 23 a man carrying a bag entered the restaurant and presented a knife to a staff member and demanded money, which a staff member handed over.
The getaway car, a grey 1992 Subaru Legacy Saloon wagon, was found by police abandoned in Selwyn Cres shortly afterward.
Yesterday police were awaiting the results of tests of items seized from the Subaru. Police are interested in suspicious activity between 8pm on June 22 and the early hours of June 23 around the Liverpool St, Victoria Ave and Selwyn Cres areas.
Anyone with information is asked to contact Crimestoppers on 0800 555 111.
