A Calwell man has been charged with stalking after allegedly deliberately crashing his car into the vehicle of a former work colleague.

Police say the 26 year old was holding a large knife when he approached the woman at her place of work in Isabella Plains yesterday – forcing her and another female colleague to flee in separate cars.

The man followed the two women in his own vehicle before allegedly slamming into both cars deliberately in Monash, causing serious damage.

Police arrested the man at the scene – seizing two large knives from his vehicle.

He’ll face the ACT Magistrates Court today.
