I don't know, but I wouldn't imagine that moving between Poland and Czech Republic is strictly monitored.
The problem is not so much the border anymore, but the fact that since Schengen, border guards can check you literally anywhere. It's not inconceviable that they might pull him in the street for a random ID check (especially as he's Indian), only to discover that he illegally entered the Czech Republic.
i could but it takes time...
For a Schengen visa? Nah, not really - you can get them pretty quickly. It might be worth actually asking the Foreigners office in wherever you are if they can give you a Schengen visa - as ridiculous as it sounds, it might just be possible.
