Later I got to know that one of my colleagues also has received the ticket while he was 'crossing' the road while 'flowering' on the phone. Apparently they had taken down all the details and ordered him to attend a training session on pedestrian rules on Sunday and in case if he doesn't attend it he would be issued summons by the courts for the 'crime'.
I am pretty lucky that I has not been picked up (still), but looks as if it will be a matter of time. So in order to find out about the law and possible punishments in Sri Lanka with respect to jay walking I tried Google and couldn't find out any detail. A friend said that the rule is that if there is a crossing within 50 meters of the place you are attempting cross, you can be issued a ticket. Not quiet sure, but any one know this rule please do share it with all the others. Seems like I deserve to be in one of the 'training'.
