A 20-year-old man has been arrested after allegedly using fake Facebook profiles to send inappropriate messages to at least two young teenage girls.
Police launched an investigation after a teenage girl in the Hutt Valley area laid a complaint last week.
The man had allegedly created at least three fictitious profiles to send the messages, which Detective Kylee Cusin said had "a sexual undertone".
One of the profiles was under the false name of Nick Davis and featured a fake photo.
Ms Cusin said a 20-year-old Upper Hutt man had been arrested and would appear in court tomorrow.
Police were still determining what charges he would face.
Ms Cusin said two teenagers had laid complaints and it was more than likely the offender had contacted others.
Police have called for any young females who have been inappropriately contacted by "Nick Davis" on Facebook to get in touch.
Wellington police spokesman Nick Bohm said police had identified a number of profiles allegedly belonging to the man.
"When you look at the number of people that those profiles are in contact with, there's a potential pool there that is quite concerning."
