Hornsby Detectives are appealing for information from the public following an assault and attempted robbery in Pymble.

About 2 pm today (Tuesday 15 May), a man, disguised by a hooded jumper, entered a business on Grandview Street and demanded money from the business-owner.

The 56-year-old owner, who was the only person working in the shop at the time, refused to hand over cash and told the hooded man to get out.

The man then grabbed a laptop from the store and attempted to leave, but he was grabbed by the owner and a wrestle between the pair ensued.

A witness from an adjoining store came to the owner’s aid and they were able to briefly detain the man, however a second man then entered the shop and attacked the owner with a wrench.

Both men then fled the store and were last seen driving in a blue Ford Falcon, west along Grandview Street.

Police were called and interviews with the owner and witness were conducted. The owner was also treated for a cut to his head, sustained as a result of being hit with the wrench.

Detectives would now like to speak to anyone who may have witnessed the attempted robbery or seen two men driving in the Pymble area in a blue Ford Falcon.

The first man is described as Caucasian in appearance, 180-185cm tall, with a slim build. At the time of the incident, he was wearing a grey-hooded jumper, black and yellow work gloves, jeans and white shoes.

The second man is described as being 30-40 years old, approximately 175cm tall with a heavy-set build. At the time of the incident, he was wearing a grey jumper, blue jeans and white shoes.
