While acknowledging receipt of your sms regarding alleged traffic signal violation, i have to bring to your kind notice, that my car no wb20u2240, is at present out of west bengal along with me and there is no question of my car violating any traffic signals in kolkata. It is apprehended that some mistake has been made in taking down the number of the vehicle that has committed the traffic violation. I would like to suggest that the colour of the vehicle be matched against the offending vehicle and that of my vehicle. I shall be obliged if i am relieved of the charges and necessary rectification be made.
