It was most likely a typo in the original article which was reproduced on SOTT. Perhaps they were confused since Kolkata is in the state of West Bengal in India. Either way, I went ahead and edited the typo.
In the future, instead of making a cryptic statement without much info about what you are exactly referring to, please be more clear and put a link to the SOTT article of interest in your post. That saves time for the person who has to search around for what he thinks, but doesn't know, you were commenting on.
