A South Australian mother of two is among more than 40 people injured after a man drove through a group of pedestrians on London’s Westminster Bridge, before driving into the grounds of Britain’s Parliament buildings and stabbed and killed a police officer.

Trish Neis-Beer, a German national who lives and works in the Adelaide Hills, is recovering in hospital after she was hit by the car driven by the attacker.

Trish's mother, Evelyn Neis-Conrad, told News Corp Australia her daughter was "safe, alive" and was "being well looked after".

"I have no idea when she can come home, as long as she comes home safe," she said.

Trish's neighbour Viv Lewis described her as a "lovely" woman and said knowing that someone she knew was involved in the attack "really brings it home".

News of her recovery comes as the identities as the three people killed in the attack - alongside the attacker himself - have been revealed.

A woman who was seen plunging from the Westminster Bridge into the Thames river during the attack has been named as 29-year-old Romanian architect Andreea Cristea, according to The Independent.

It remains unclear whether Cristea leapt from the bridge as a result of her injuries, or to avoid being hit by the car as it drove through a group of pedestrians.

Romanian Ambassador Dan Mihalache said the woman sustained serious head injuries and has badly damaged lungs as a result of the fall.

She was rescued from the water by a City Cruises boat, whose crew spotted her body floating downstream.

She is currently fighting for her life in hospital, and is said to be in a serious condition.

So far, seven people have been arrested after overnight raids were conducted following the attack at Westminster.
