The surrender of a cache of weapons including three grenades that triggered the evacuation of a Gold Coast office block is being probed by police.
Specialist officers have revoked an emergency declaration after a man surrendered three grenades and three semi-automatic rifles at a lawyer's office on Bay St, Southport, on Wednesday.
The streets around Bay St, where a number of lawyers' offices are located, were roped off and residents in the exclusion zone were urged to stay in their homes for three hours.
No threats were made during the incident.
Gold Coast Police district duty officer Jim Winter says the grenades and rifles have been rendered safe and the street has been reopened, but detectives are investigating the incident.
"They are trying to track that person down to ask why they were delivered here and not [to] a police station," he told ABC online.
"All semi-automatic rifles are illegal in Australia as far as I am aware, definitely they are in Queensland."
