The Worcester County Sheriff's Office in Maryland shared a Facebook post urging the community to stay vigilant and report suspicious activity around propane storage or distribution facilities. 

The Sheriff's Office was alerted to suspicious activity at the Sharp Energy Facility Plant in Princess Anne, Maryland on January 3. 

An employee at the plant watched the driver and passenger of a dark blue Tesla park in the middle of one of the entrances to the plant and exit the car with "high-tech" cameras with long lenses. The employee said the two people took pictures of storage tanks and rail cars. According to the Sheriff's Office, when the people were spotted, they jumped back into the car and drove away. 

The Facebook post states there may have been a third person in the Tesla. 

The Sheriff's Office is asking people to watch for: 

• Unfamiliar individuals loitering near propane facilities. 
• Unmarked vehicles parked for extended periods of time near facilities like this. 
• Unauthorized personnel trying to access restricted areas. 
• Odd behavior, such as photographing, taking notes or closely inspecting tanks or equipment. 

The Sheriff's Office is asking folks to: 

• Stay Alert: If you live or work near a propane facility, keep an eye out for anything unusual. 
• Report Suspicious Activity: Call your local law enforcement agency. Provide a description of the enforcement agency. Provide a description of the person, vehicle or behavior. 
• Avoid Confrontation: Do not approach or engage suspicious individuals.
