A woman has fallen to her death in a shopping centre, landing near terrified shoppers.

Police were called to Westfield Parramatta, in Sydney’s West, at about 1.05pm where they found the woman.

According to reports posted by terrified shoppers online, she had fallen from an upper level of the shopping centre to the ground floor.

A woman posting online said the woman landed near her and nearby children.

The woman said barriers were erected around the woman.

Areas of the Westfield shopping centre, in Parramatta, 20 kilometres west of Sydney, have since been cordoned off as police investigate the incident.

“I thought it was terrorists — I heard ‘BANG’, it sounded like a bomb or something,” a witness told The Daily Mail.

Counselling services have been made available for those affected by the tragedy, a spokesperson for the centre told news.com.au.

“The welfare and safety of our customers, retailer partners and people is our priority,” a spokesperson from Scentre Group, who operates Westfield Parramatta told news.com.au in a statement.

“We have made support and counselling services available to those who need it.

“We would encourage anyone who may need support to contact our centre management office directly.”
