NSW police carrying out raids at Sydney Olympic Park

NSW Police are conducting raids on a number of premises across Sydney. 

Witnesses say heavily-armed police stormed an area around the Ibis Hotel in Sydney Olympic Park just after midday on Tuesday.

Brian Clark, who works in the area, said he saw a male and female taken into custody outside the hotel.

They were surrounded by dozens of uniformed and non-uniformed police. He said he believed the Australian Federal Police and riot police were involved.

"Whatever was going on, the police had it really locked down. They were calm and in control," he said. "They took the two people away without any fuss."

A police spokesman said: "A police operation is currently underway involving multiple search warrants across Sydney. As the operation is ongoing no further information is available".
