As it seems right now, it is difficult to very whether Mr. Azhar has been detained by the Pakistani authorities or not.  It depends who you ask.  Pakistani authorities and its press are confirming that he is detained, but if you ask the Indian press and the Indian government officials,there seems to be some apprehension in this matter. I am sure this riddle will have its answer pretty soon.  Giving Pakistan a benefit of doubt, let us assume that he is detained.  Then, it is definitely a positive step - a step in the right direction to improve relationship between India and Pakistan.  But in the eyes of this writer, just arresting him along with his colleagues who were involved in the Pathankot attack is not enough.  The sincerity of Pakistan government will be revealed on the type of punishment given to this group, especially to Mr. Azhar.  This is not the only crime Mr. Azhar has orchestrated against India.  He has a history of crimes where he was instrumental in harming India vis-a-vis attack on the Indian Parliament in 2001 and also his involvement in the 26/11 Mumbai attack.  In fact, he should be handed over to the Indian government  so that he can face an appropriate legal music in India.  Till Pakistan's final action and judgement do not surface openly, India ought not to be satisfied, and also India should make it clear to Pakistan now that this was the third strike.  No more strikes will be tolerated by India, and if it happens, there will be an open all out war.
