Man set upon on Gold Coast street

Four men who were trying to buy drugs on a Gold Coast street have bashed and robbed a man who said he couldn't help them.

Police say the 49-year-old was walking along Marine Parade, Southport around 7.30pm on Wednesday when he was approached by one of the men wanting drugs.

As he tried to move away, he was punched to the ground then kicked a number of times, before they fled with his bag. He's been treated in hospital.
