A young man has been arrested after numerous reports of a man exposing himself and groping women in Canberra's north.

A girl was walking her dog about 5.20pm on Monday in Evatt when she was approached by a male who pulled his pants down and exposed himself. The man attempted to reach out to the girl before she screamed and fled the area.

In a statement, police said it was believed the incident was linked to four similar incidents across the weekend in McKellar, by Lake Ginninderra, and at a University of Canberra residence.

The first incident occurred in a McKellar home shortly before midday on Saturday. A man entered the laundry of the home, grabbed a woman and indecently assaulted her before fleeing.

About 10 minutes later, another McKellar resident reported a man attempting to gain entry to their home. He was heard banging on windows and doors, but he couldn’t get in and soon left.

Another two incidents were reported on Sunday, one by Lake Ginninderra just after 6pm, when a man rode past a woman and tried to grab her. He later returned and performed an indecent act in front of her before riding off

ACT Policing attended the scene in Evatt on Monday night and executed a search warrant on a home in Canberra's north.

A young man was arrested and charged with committing an act of indecency. He will appear before the ACT Children's Court on Tuesday morning and police will oppose bail.
