A woman has been grabbed from behind and indecently assaulted by a half-naked man during a late night walk in Sydney's east.
The 28-year-old was jumped by the man after turning off New South Head Road about 1am (AEST) Sunday, police say.
She then managed to break the man's grip before running across the road to seek help.
When the man attacked her he was "naked from the waist down", police said in a statement.
They believe the man started following her when the pair crossed paths in Paddington about 15 minutes earlier.
A search for the man, who was last seen running along Mona Road in Darling Point, is underway.
He is described as being aged between 30 and 45, of medium build and was wearing a black beanie and jacket.
