In October 2011 he was charged with being drunk and disorderly in Newcastle's Cathedral Square. The charge came only days after Ranger had been reinstated to Newcastle United's first-team training after a three-month exile in the club's reserves.[26] In March 2012 he was convicted of being drunk and disorderly and was given a six-month conditional discharge and ordered to pay £135 costs.[27][better source needed] Prior to this, in May 2011 Ranger was questioned by Newcastle after posing with a replica gun in a photograph.[28][29] The gun was later handed in.[30][better source needed]

In the early hours of 23 September 2012, police were called to a house in Enfield, north London after reports of a disturbance. The front door of the property was badly damaged and Ranger was arrested at the scene and later charged with criminal damage.[32] The charge against Ranger was dropped in November 2012 after the court accepted his explanation that he had damaged the door after fearing his girlfriend was being kidnapped.[33]
On 25 January 2013, Ranger was arrested on suspicion of rape in a Newcastle hotel room.[34] In connection with the same alleged offence, Ranger was charged with rape on 8 July 2013.[35] On 4 March 2014 he was cleared of the charge at Newcastle Crown Court.[36]

On 3 January 2014, Swindon Town chairman Lee Power confirmed in a press conference that the club would be meeting with Ranger and his management in the following days to confirm his sacking due to his disrespect shown towards the club through constant absence during training. Power said "I'm the chairman of the club and I've got to do what's best for the club. Unfortunately, what's best for the club is having to sit down with Nile and talk about parting ways. While this is ongoing Nile is not training with the squad."[39]
On 23 March 2014, Ranger was arrested on suspicion of causing criminal damage to a taxi in Liverpool.[40]
