A doorbell camera captured the moment a man working on a school sport field was struck - by a bolt of lightning. <br /><br />The man was painting lines on a soccer field during a storm when he was hit.<br /><br />A responding police officer administered CPR potentially - saving his life.<br /><br />Eric Baumgartner, 39, an employee of Iselin Middle School in Woodbridge, New Jersey, USA was struck in the foot and "was not moving," according to witnesses.<br /><br />Responding police officer R.J. McPartland jumped into action when he realised that Baumgartner didn't have a pulse and performed CPR.<br /><br />McPartland said: "We were able to see some burn marks appeared on his hands, so that was how we were able to determine what happened. <br /><br />"And we knew we needed to start compressions to get his heart started again.<br /><br />"We were trying to talk to him the whole time. <br /><br />"Once we were in the ambulance and did he get a pulse back, he did slowly begin to regain consciousness.<br /><br />"It's what we're trained to do. Luckily, we are trained in that and were able to provide that to someone who needs it."<br /><br />Woodbridge Mayor John McCormick said: "As of right now, I have every reason to believe R.J. McPartland saved Eric Baumgartner's life."<br /><br />Baumgartner is said to be in a stable condition at Robert Wood Johnson Hospital.
