Pregnant Woman Bashed, Thrown Into Pole In Unprovoked Attack

Police have arrested a woman over a "vicious" and unprovoked attack on a heavily pregnant woman, on a busy Sydney street during morning peak hour.

A NSW Police officer, who happened to be passing by, arrested the 28-year-old alleged attacker after she leapt upon the other woman as she walked on a footpath on Tuesday morning. Another pedestrian intervened to stop the attack.

The alleged victim, who is 30 weeks pregnant, was walking along Wentworth Avenue in Surry Hills just before 9am on Tuesday.

"Without provocation, another woman emerged from an alcove and repeatedly punched her in the head. The assailant allegedly pulled the victim’s hair and rammed her into a power pole," NSW Police said in a statement.

"The victim, clutching her womb, fell onto the roadside and was helped to safety by a passer-by, who wrestled her away from the attacker."

The alleged attacker was pulled from her victim by another man, with CCTV of the incident showing her pointing and yelling at the pregnant woman as she left her prone on the roadside.

An off-duty probationary police officer had been walking past at the time, and arrested the alleged attacker, a Mount Druitt woman.

She was later charged with assault occasioning actual bodily harm, was refused police bail, and appeared court later on Tuesday where she was ordered to remain in custody.

The alleged victim has been taken to hospital. Her condition is not known.

"The civilian did not hesitate to leap to the rescue of the pregnant woman and we commend his bravery,” said Detective Chief Inspector Adam Johnson said.

“We would also like to praise the swift response of the probationary constable who saved the woman from further harm."

Johnson added that it was an "unprovoked, unwarranted and unnecessary attack."
