Police in Port Lincoln, South Australia, are investigating two incidents that occurred early on Saturday morning and may involve the same offender.

At about 4:40am on September 26, police were called to a business on New West Road after an alarm was activated and a man was reportedly seen inside the premises. The owner attended the business after receiving the alarm notification and disturbed the alleged intruder.

The man reportedly fled the premises on foot before police arrived. According to police, nothing was stolen during the first incident.

A short time later, just after 5am, police received another report from a service station on Hallett Place. Staff reported that a man armed with scissors had threatened employees before allegedly stealing cash and cigarettes.

The suspect again left the scene on foot. Police said no staff members were physically injured during the robbery.

Investigators believe the two incidents may be connected and are examining available evidence to determine whether the same person was responsible for both events. Police have released a description of the person they are seeking as part of the investigation.

The man was described as wearing a black puffer or parka-style jacket, a blue baseball cap featuring a gorilla motif and dark shorts.

Police are appealing for anyone who witnessed suspicious activity around New West Road or Hallett Place during the early hours of Saturday morning to contact investigators. CCTV footage or other information from nearby businesses and residents may also assist the investigation.

The incidents occurred within a relatively short period and involved two different businesses. The second incident escalated when staff were allegedly threatened with scissors, although police have confirmed that no employees suffered physical injuries.

Investigators will now work to establish the movements of the suspect between the two locations and examine evidence collected from both scenes.

The investigation remains ongoing, and police have not announced that anyone has been arrested in connection with the incidents at the time of the report.

For local businesses, the incidents highlight the importance of security systems such as alarms and CCTV, which can provide investigators with useful information after overnight break-ins and robberies.

Police are continuing inquiries and may provide further information as the investigation develops.

Anyone with information relevant to the case should contact South Australia Police.
