Thieves have looted expensive Apple computers and iPads after breaking into at least eight Melbourne offices by prying concrete Telstra pit lids from the footpaths and hurling them through windows.
Detectives say the string of break-ins were all at offices in the City of Boroondara, in Melbourne's inner east, and spanned three weeks from March 28 to April 13.
Four offices on Canterbury Road in Surrey Hills were among those that were ransacked.
The thieves also targeted offices in Union Road in Surrey Hills, High Street in Kew, Shierlaw Avenue in Canterbury and Riversdale Road in Hawthorn.
''On each occasion, the offenders have used a Telstra pit lid to gain entry to the premises and once inside have stolen Apple electrical products,'' a police spokeswoman said.
Boroondara detectives will release CCTV images of two men they want to question over the commercial burglaries, which they say are linked.
One of the men is described as having a large build, a bald head and is possibly of Middle Eastern or Southern European descent.
The other man is described as tall with a slim build.
