Welcome to The AnswerBank, Ankimo!

Sorry, I can't help directly but it might help others here to be able to take a closer look at it:

It might also help to know which country you're in, as many insects are only found in specific areas of the world. (You've posted on a UK-based website but the timing of your post suggests that you might be elsewhere in the world).

I hope that you get an answer soon.

Hmmm.

Having used my enlargement for a Google reverse image search, I'm minded to think that it could well be a tropical house cricket (or, at least, a very similar species), especially if you're in India or southwestern Asia:

Crickets are harmless to humans.

I agree with that answer, it looks like a cricket of some kind.
I'v seen something similar in the UK, known as the bush cricket, that is bright green.
