Professional basketballer Luke Martin has been denied bail over allegedly throwing rocks through the windows of Sydney's Lindt cafe and breaking a police officer's jaw during the subsequent arrest.

Martin, who has represented Australia with national team the Boomers, was alleged to have thrown a number of rocks through the windows of the chocolate shop overnight.

The cafe recently reopened after major renovations, after being the site of a siege last year which left three dead, including attacker Man Monis.

Police said they observed a man allegedly driving erratically in Sydney CBD just before midnight. Police followed the vehicle to the nearby suburb of Darlinghurst.

Police will allege the driver left the vehicle and threw a bag, from the back of the car, at officers.

During the arrest, a male constable was allegedly assaulted. He suffered a broken jaw, and swelling to his knee and remains in hospital.

While Martin, 34, was being questioned at Kings Cross station, detectives investigating the Martin Place attack, after viewing CCTV images, charged him with malicious damage over the cafe incident.

He has also been charged with driving in a dangerous manner, police pursuit, assaulting police occasioning actual bodily harm and resisting arrest.

He was denied bail in Central Local Court today and will reappear in court on June 12.

Martin represented Australia as a member of the Boomers in 2004 and 2005, and has played for the Sydney Kings.

He is currently contracted to the Brisbane Spartans.

Police Commissioner Andrew Scipione said the alleged attack was "outrageous", but seemingly unrelated to the siege or the current inquest.

Police said it is being treated as a case of malicious damage.

"Any attack on that particular location is outrageous," Mr Scipione said.

Police Minister Troy Grant said he shared Mr Scipione's "disgust".

"I'm relieved that it's not related to the events of last year," he said.

"It's a significant place in our nation's history now, because of the terrible events that occurred."

Meanwhile, an inquest into the Lindt cafe siege continues today, as further details emerge about killer Man Haron Monis.
