Five pedestrians are reportedly injured after a car drove into the Cup Thai restaurant at Chatswood, northern Sydney, this morning.

A woman was rushed to hospital in a serious condition, with four others – including an infant – also being taken for treatment.

Early reports suggested the incident was not terror-related.

A statement from New South Wales Police later said: "The incident was not a deliberate act and it's believed the man may have suffered a medical episode."

The incident happened at 3.45pm local time (5.45am UK time).

Neville Yates‏ wrote on Twitter: "Just saw three people mowed down at the bottom of chatswood mall. Looks like driver had passed out. Three women hurt, hopefully ok."

Ching Xu told 7 News Sydney: "I was sitting down, and then when I looked up I could just hear screaming and could see the car coming up and hitting someone."

Police say they have established an exclusion zone and the male driver is assisting them.

The incident comes nearly 48 hours after a double terror attack struck Barcelona and left at least 14 dead and 130 injured.

It also comes just hours after a knife wielding man went on a stabbing rampage in Finland and left two dead.
