Police link Sydney stab attacks

The stabbing of a shop attendant in Sydney last year has been linked to another attack in the city last month.

A 35-year-old man was threatened with a knife and stabbed in the shoulder during a robbery at a Buckland Street, Chippendale convenience store on December 19 last year.

A 29-year-old woman was threatened with a knife by a man in a store in Bulwara Road, Ultimo on March 27, police said on Wednesday.

She was uninjured, while the man fled with cash and cigarettes.

Police have released CCTV of a man seen in the vicinity of the Chippendale attack.
