NEW DELHI: The Congress on Thursday alleged serious security breach in party president's security cover and said that there is a threat to Rahul Gandhi ’s life in Amethi .The Congress has written to the ministry of home affairs ( MHA ) regarding the matter.In its letter to the MHA, the Congress claimed that green laser, possibly from a sniper gun, was pointed at Rahul Gandhi's head, during a media interaction in Amethi on Wednesday.The Congress president is an SPG protectee.“A perusal of the video by various persons including former security personnel leads to a prima facie conclusion that this laser could emanate from a potential weapon such as a sniper gun,” the letter said, referring to a video clip of Rahul’s interaction with the media, which has also been provided to the MHA.“We urge you to immediately take note of this grave and unacceptable security threat as also the security lapse in the security of the Congress president. This is also an alarming lapse on part of the UP administration which is responsible for the peripheral security,” the Congress letter said, jointly undersigned by Ahmed Patel, Jairam Ramesh and Randeep Singh Surjewala.However, the MHA said that it has not received any letter regarding the alleged breach in the security of Rahul Gandhi. "As soon as the MHA’s attention was drawn to reports of the incident of 'green light' being pointed at him in Amethi, the director (SPG) was asked to verify factual position."The MHA further added, "Director SPG has informed the MHA that the 'green light' shown in the clipping was found to be that of a mobile phone used by AICC photographer, who was video graphing the impromptu press interaction of Rahul Gandhi near the collectorate in Amethi."Rahul Gandhi filed his nomination papers for Amethi Lok Sabha constituency yesterday. Prior to filing his nomination, he also conducted a roadshow in Amethi where Priyanka Gandhi Vadra accompanied him.
