<p><br /> A man living in Germany was shot in the back of his head - but did not realise until five years later.<br /> </p><p><br /> The 35-year-old was hit by a .22-calibre bullet as he was out in the street partying on New Year's Eve in the western town of Herne.<br /> </p><p><br /> "My first thought was as if I had banged my head against something or that I was hurt by a firecracker, a small firework. I did not notice it," said Robert Chojecki.<br /> </p><p><br /> He didn't seek medical assistance at the time and only went to see a doctor recently when he started getting headaches.<br /> </p><p><br /> Doctors took an X-ray and found the bullet lodged between his skin and cranial bone.<br /> </p><p><br /> Police say the projectile may have been a stray bullet fired by a reveller in celebration.<br /> </p>
