A �10,000 reward is being offered to anyone with information that leads to the arrest and conviction of gang members who carried out a brutal robbery.

On the night of July 23 this year, seven masked men armed with crowbars and hammers burst into a house in Bedwell Avenue, Essendon.

They tied up the woman who lives there and smashed her repeatedly in the face with a brick, before dragging her two petrified daughters outside and threatening to drown them in the property’s swimming pool.

The gang stole cash, jewellery and the 42-year-old victim’s silver Range Rover.

They abandoned that 200 metres down the driveway before escaping in another vehicle.

The woman was hospitalised with facial injuries after the raid, which happened just before midnight.

Detectives investigating the crime this week revealed the cash reward is being offered as an incentive for people to come forward.

Detective sergeant Lee Waller said: “This was a terrifying ordeal for the woman to go through and we are determined to find those responsible and bring them to justice.

“We are currently following a line of enquiry that this was not a random incident.

“I am appealing for anyone who may have information regarding this crime to come forward as soon as possible and I am hoping the reward of up to �10,000 will encourage people to get in touch.”

He added: “I would like to stress there will be no ramifications for you if you do supply information as there is no chance you will be identified.

“Any information you provide, no matter how insignificant it may seem, could really help us to solve this terrible crime and bring those responsible to justice.”
