Northern Territory Police are calling for information in relation to an unlawful entry yesterday at a Tourist Park on Larapinta Drive.
About 3:30am, four males approached the reception building, causing damage to the front window and security screen. One of the males entered the building, locating a secured alcohol before passing several bottles through the window to the group outside.
Upon hearing the disturbance, the occupant entered the office area and was confronted by the offender.
The offender allegedly armed himself with a chair and threw it at the victim, before the victim performed a citizen arrest. The 21-year-old was taken to Alice Springs Watch House by police.
The three other offenders outside the building fled the location.
Strike Force Viper Investigations are ongoing to identify and locate the outstanding offenders.
Anyone with information about the incident or the identities of the three remaining offenders is urged to contact police on 131 444 or CrimeStoppers on 1800 333 000.
