Last week South Korean prosecutors formally charged the man who injured Lippert with attempted murder on Wednesday - despite his denials of any intention to kill. Last week South Korean prosecutors formally charged Kim Ki-Jong with attempted murder . The prosecutors' office in Seoul said Kim, was charged with attempted murder, violence against a foreign envoy and obstruction of duty. Kim, 55, was a known maverick activist who had been handed a two-year suspended sentence in 2010 for hurling a rock at the then Japanese ambassador to Seoul. He has denied any intention to kill Lippert, but the prosecutors office said in a statement that the crime was clearly deliberate. 'There was an intention to murder because (Kim) used a lethal weapon in a pre-meditated crime to attack the ambassador's face and neck repeatedly,' it said. Kim has told investigators the ambassador was the 'symbolic' target of his opposition to annual US-South Korea joint military exercises, which he blames for blocking dialogue with North Korea. The annual drills have long been condemned by Pyongyang as rehearsals for invasion. Kim insisted he had acted alone and not on the orders of Pyongyang, but prosecutors said they were looking into whether he has violated the South's strict National Security Law banning any act seen as aiding North Korea or promoting its ideology. Investigators have ransacked Kim's home as part of an investigation into Kim's possible links with North Korea. Kim had visited the North seven times and once tried to erect a memorial in Seoul to the late North Korean leader Kim Jong-Il after his death in 2011. North Korea has rejected accusations that it may have been behind the attack as a 'vicious' smear campaign by Seoul.
