Three females, one as young as 14, have been arrested for allegedly assaulting and robbing a 101-year-old man in a mobility scooter on Mitchell Street last night, NT Police said.

The elderly man was allegedly held by the females around 9:30pm, who removed his wallet and keys before fleeing the area.

The victim suffered cuts to his arms in the assault and was taken to Royal Darwin Hospital for treatment, police said.

All three girls, aged 14, 15, and 19, were located later by police CCTV operators at a location near the scene of the crime and arrested. They were later charged on Wednesday with aggravated robbery and depriving a person of personal liberty, police said.
