Police have charged a 21-year-old woman over an alleged attack on a toddler at a shopping centre.

WA Police confirmed on Wednesday that a woman had been arrested over the incident.

“Please be advised a 21-year-old female was taken into custody at Mirrabooka Shopping Centre about 11.10am,” a police spokesperson said.

On Wednesday afternoon police confirmed they had charged the woman they had arrested.

“A 21-year-old women from Ellenbrook has been charged with one count of aggravated assault occasioning bodily harm,” police said in a statement.

She will appear before the Perth Magistrates Court on Thursday.

Cannington detectives launched an intense search for Pamila-Raye Jetta, 21, in relation to the alleged attack at the Park Centre on Albany Highway in East Victoria Park about 1.25pm on Tuesday.

A terrified mum was holding her two-year-old daughter when a woman approached and struck the child before fleeing.

The little girl had facial injuries.

Premier Roger Cook on Wednesday said he was “appalled” by the footage of the assault.

“It’s a shocking, shocking situation where a mother with her very vulnerable child, minding their own business, is subject to assault. It must be incredibly traumatic for the mother and, of course, potentially very serious injuries for the baby involved,” he said.

“I’m so pleased that the police have now taken someone into custody and that this situation can be resolved as soon as possible.

“But I think we’re all appalled and shocked by the footage … and I just hope the mother and the baby are well and wish them all the very best.”

It comes weeks after another shocking attack on nine-month-old Luka when a stranger allegedly poured a Thermos of hot water on the youngster’s face while picnicking with his mother in Brisbane.

The boy suffered burns to his face and chest.

A 33-year-old was identified by Chinese media after allegedly fleeing Australia. A warrant has been issued for his arrest.
