<p><br /> Police involved in a stand-off with gunman Raoul Moat are understood to have used two Taser stun guns, the police watchdog has said.<br /> </p><p><br /> An Independent Police Complaints Commission (IPCC) spokesman said that two Tasers were discharged by officers during the tense siege between police and the former nightclub doorman.<br /> </p><p><br /> Moat, 37, shot himself in the head after being surrounded by armed police in the early hours of Saturday morning. It followed a tense six-hour stand-off sparked when he was spotted on the riverbank in Rothbury, Northumbria.<br /> </p><p><br /> According to an eyewitness the stand-off ended when police surrounded Moat and jumped on him.<br /> </p><p><br /> Mr Long said: "Early indications show that gunshots were not fired by police officers and this will of course form part of the IPCC independent investigation. It is also understood that a police officer discharged a Taser and our investigation will also look at this.<br /> </p><p><br /> "The IPCC has now two independent investigations. The first relates to the intelligence from the prison authorities on Mr Moat's release and the second his death. I have decided that there will be one investigation covering both these aspects.<br /> </p><p><br /> "We will be examining whether correct procedures were followed by Northumbria Police and the detail of how this incident came to a conclusion.<br /> </p><p><br /> "A full investigation will now be carried out and we will publish our findings in due course so that there is a public account answering the many questions that people will have."<br /> </p><p><br /> Mr Long, who also sent his sympathies to the people affected by the events of the last week, said that the IPCC launched their investigations after they were contacted by Northumbria Police.<br /> </p>
