Lets be rational.Its not a question of a muslim or any other community person being picked up.Police has to investigate.Definitely they have some reasons to suspect certain individual thats why they pick them up.What do you think, if they donot pick up and question anybody depending on any clue they have , how will they find the right culprit?Yes there shouldn't be detentions as mentioned above.The family members should be kept informed.Whenever any mischief is done Isn't a Hindu picked up or haven't you heard a sikh picked up?? So why to make nonsense cries for a muslim guy specially, which only promotes communal hatred.
