Police are investigating the break and enter of a postal business at Burleigh Waters early this morning.

Around 3.25am two men used what appeared to be a sledge hammer to smash their way through the front glass doors of the premises on Classic Way. 

Once inside the men stole a quantity of prepaid and express envelopes before before making their getaway.

Police are keen to hear from any members of the public who may have seen anything suspicious in the area around the time of the incident.
