Man charged over terrifying attack on pregnant woman

A man has been charged over violently punching a pregnant woman and threatening her with a knife outside her Sydney home.

Mother-of-three Ashley, 24, told Sunrise she was approached by three men, one of whom grabbed her by the neck and dragged her out of the car after she arrived home following a night out.

"When he dragged me out of the car he picked me up by my neck and threw me against the side of a car and punched me in the stomach.

"That's when he dragged me around and to the front, held me at knifepoint, and whispering in her ear telling me to open the front door."

The incident happened at 1.30am on Friday in Federal Road, Seven Hills.

The trio were not able to get into the home and fled the scene in the woman's Commodore sedan, which was later found burnt out in Toongabbie, police said.

The car has been towed for forensic examination and a crime scene has been established at the home, detectives are investigating.

Ashley told Sunrise that she believed she knew one of the men.

One of the suspects is described as being of Caucasian appearance about 30 years old, with a medium build, moustache, goatee and short hair.

The other men were only described as speaking with a “New Zealand” accent.

Police are urging anyone with information in relation to this incident to call Crime Stoppers on 1800 333 000.
