Detectives investigating two ram-raids near Nowra have found several items of interest, which could be connected to the robberies, in a nearby waterway.
On April 10, the owner of a service station on the Princes Highway in Falls Creek arrived at the store to find it had been broken into and a large safe, containing cash, along with numerous cartons of cigarettes was missing.
The property had also been seriously damaged.
Four days later, police were called to a service station on the Princes Highway in Wandandian after reports of a ram-raid robbery.
Police claim several men in a white Toyota Hilux ute reversed through the front door of the service station, before using chains and a sledgehammer to dislodge an in-store ATM and hoist it onto the rear of the ute.
Two staff members, who interrupted the robbery, were allegedly threatened with the sledge hammer and chain.
The men – who were disguised by black clothing and balaclavas – then fled the scene in the ute.
They were last seen heading north on the Princes Highway.
Detectives formed Strike Force Lagul to investigate the robberies and believe the same group are responsible for both offences.
On Monday, police divers conducted a search of Tomerong Creek and located several items that may be connected to the ram-raids.
Detectives are appealing for anyone with information to contact Crime Stoppers on 1800 333 000.
