I was sat thinking why you were stood there before I was took away by the word police [duplicate]

"He was took" is not technically correct English. If you wrote it in an English exam (even in the North of England) you would be marked down for it. I would never recommend using it in any kind of formal communication. The same is true of "I was sat".

However "not technically correct" does not mean "isn't used", or even "shouldn't be used". All of these are common in different parts of England, and some would consider them "dialects" of English, and those terms correct within that dialect.

So my recommendation is to learn to love and understand the variant grammar, but don't use it in a job application.
