Sydney man linked to indecent assaults

Images have been released of a man believed to be linked to several indecent assaults in Sydney's north.

In one incident in May 2014, an 18-year-old woman was indecently assaulted at Lindfield, while a 30-year-old woman was grabbed from behind by an unknown man in the neighbouring suburb of Killara in November 2014.

Police have released CCTV footage of a man of Asian appearance with a slim build and short black hair, who they believe is linked to the assaults.
