A 79-year-old man was assaulted by a group of five male youths during a home invasion in Tennant Creek, with the offenders still on the run, NT Police said.

Police director of communications Mark Wilton said police were looking for information after the aggravated robbery in the town on Thursday night.

He said that about 8:20pm, police received reports that five male youths allegedly broke into a Scheelite Street home, with one of the alleged offenders armed with an specified edged weapon.

“The sole-occupant, a 79-year-old male, was threatened before being physically assaulted by the offenders,” Mr Wilton said.

“The offenders subsequently rummaged through the property, stole the victim’s phone, and fled the scene.”

Mr Wilton said the man suffered minor hand injuries and received medical treatment, but did not say if he had been stabbed, while the offenders were still on the run.
