Saw this spider behind the washer in my 12th floor apartment located in Islamabad, Pakistan.
Islamabad is located very close to the Margalla hills that are part of Himalayan Mountain range. This area has a lot of vegetation and good rainfall too

Size of this spider from one side to the other is around 3.5 centimeters.

Is this spider dangerous? If yes, how do I carefully catch it and release it into the jungle?
