A female has suffered a stab wound following an alleged carjacking in Belconnen this morning.

At about 11.30am, ACT Policing responded to reports of an aggravated robbery in the top level of the multi-story car park of a Belconnen Westfield.

A crime scene was established with forensic police examining the scene this afternoon.

The stolen vehicle was subsequently sighted a short time later in Braddon, and the man was arrested about 11.50am in Ainslie following a short foot pursuit.
