<p><br /> A police sergeant who injured a woman when he assaulted her in a cell has been jailed for six months.<br /> </p><p><br /> Sgt Mark Andrews was caught on CCTV dragging Pamela Somerville, 59, across the floor of Melksham police station in Wiltshire before shoving her into the cell.<br /> </p><p><br /> Ms Somerville was arrested in July 2008 after being found asleep in her car. She was detained for failing to provide a sample for a breath test.<br /> </p><p><br /> The CCTV footage shows her lying on the floor for a minute before struggling to get up with blood pouring from a head wound.<br /> </p><p><br /> Former soldier Andrews was convicted of assault causing actual bodily harm after a trial at Oxford Magistrates' Court in July. The 37-year-old, who was suspended on full pay after his conviction, was sentenced at the same court.<br /> </p><p><br /> Ms Somerville was taken to Royal United Hospital in Bath and needed stitches in a gash above her eye.<br /> </p><p><br /> Ms Somerville, a market researcher from Chippenham, Wiltshire, described the attack as a "horrific nightmare". She said: "I will never forget it. I would love to be able to take a tablet to make me forget it but I never will. It was just a horrific nightmare. I thought they had mistaken me with a murderer or drug smuggler or terrorist."<br /> </p><p><br /> She said she wanted to move on from the attack but called for Andrews to make a personal apology: "I would like him to say sorry and I would like him to do it personally - I think that's the least anybody could do," she said.<br /> </p>
