A 22-year-old male is in custody after he allegedly indecently assaulted a woman at a Katherine shopping centre at 8am this morning, NT Police said.

Police said the man assaulted the woman who was not known to him at a shopping centre on Katherine Terrace, and was arrested “a short time later”.

He was expected to be charged with indecent assault.

Police said the man was wearing a baseball cap with the words “Zero Harm” embroidered on it, as well as a black Air Jordan singlet with red trim, long tan pants and sunglasses.

It appeared in a statement that police are unsure if the man had committed any other assaults.

“Police want to reassure the community this individual is now in custody and will face court for his actions,” said Acting Superintendent Scott Warren.

“We are calling for anyone with information, particularly if you saw someone matching the description of the male, to contact police on 131 444. Please quote reference 10101536.

“You can also anonymously report through Crime Stoppers on 1800 333 000.”
