A company director who is believed to have committed suicide "wasn't the man he was" after his firm was criticised for supplying the Tasers used during the stand-off with gunman Raoul Moat, his business partner has said.

Peter Boatman, who was director of operations for Pro-Tect Systems, was found dead at his Northampton home earlier today and is understood to have committed suicide.

The Home Office revoked the firm's licence to import and sell Tasers on Tuesday after it breached its terms by supplying X12 Tasers, which were still being tested by Government scientists, directly to police involved in the Moat manhunt.

Pro-Tect was facing possible action by Northamptonshire Police over the breach of the licence.

Speaking on Tuesday, Superintendent Sean Bell, the force's head of operations, said the force was "considering whether or not to take further action against Pro-Tect in connection with breaching the conditions of their licence".

Former police officer Mr Boatman, 57, was previously in charge of assessing the merits of Taser as head of operational training for the Northants force before leaving to join Pro-Tect.

Home Secretary Theresa May revoked the firm's licence to import and sell Tasers following an investigation into the use of the weapons at the end of one of Britain's biggest manhunts.
