A man who grabbed a woman from behind late last year in southwest Sydney had stalked her only two days before, police say.
On December 10, he grabbed the 31-year-old near Belmore Railway Station, covered her mouth with his hand and tried to drag her toward a unit block before she broke free and ran.
Two days earlier, on December 8, the same woman became spooked and ran after being followed by a man walking closely behind her.
A later examination of CCTV footage by NSW Police found that on the night of December 10 another unidentified woman was followed by the same man and escaped by seeking refuge in the front yard of a house.
"The man walks past the house, before turning back and heading towards the station," police said in a statement on Wednesday.
Then police discovered the same man was seen following a number of other women in the same area over two hours on December 22.
"He has not been seen at the station since," police said.
Detectives have released CCTV footage of the man and are asking anyone with information to come forward.
