HENRY COUNTY, Ga. -- Authorities are trying to figure out who targeted three Henry County fire departments early Tuesday morning.

The Henry County Police Department is investigating the thefts, where missing personal property and damage to county vehicles were reported. No other information is available at this time.

Fire department officials said they are working closely with county leaders and law enforcement to ensure that facilities stay safe and secure.

These recent thefts are just the latest in a series of recent incidents targeting first responders and public safety facilities.

Last month, seven police cars were vandalized downtown and another fire station was targeted in East Point.

In February, someone vandalized firefighters personal cars at Fire Station 29 in northeast Atlanta, just one month after intruders broke into Gwinnett County firefighters' vehicles. In that incident, thieves stole personal weapons and other valuables. Thieves struck another time in January at a Forsyth County fire station.

Police and fire departments are reluctant to speak about what they're doing to increase security, not wanting to tip off criminals.

"You realize these guys are here working hard, 24-hours at a time away from their families, serving the public, protecting everyone, including the bad guys that broke into their vehicles,” Forsyth County Fire Department's Division Chief Jason Shivers said. “And then to be a victim of something like this is terribly disheartening."

Anyone with information regarding the break-ins at the Henry County fire stations is asked to call police at 770-957-9121.
