Hamilton police are urging parents to take more responsibility for their teenage daughters after a spate of crimes.
The call comes after two aggravated robberies involving teenage girls overnight.
The first incident happened outside a fast food restaurant on Ward St about 9.30pm, said Hamilton city area commander, Inspector Rob Lindsay.
"Two girls, aged 15 and 17, beat up an 18-year-old girl and robbed her of her wallet.
"In the second incident, three girls, two aged 15 and one 16, armed with a sharpened weapon, robbed a male taxi driver of $10 on Norton Rd about 1.30am," Mr Lindsay said.
Five girls had been arrested and faced aggravated robbery charges in Hamilton Youth Court.
Mr Lindsay said last night's incidents were just the latest in a series of serious incidents involving girls.
Other incidents included several arrests of highly intoxicated youths over the weekend, many of them girls, involved in fights.
The weekend before several girls were involved in a large scale fight at the Balloons Over Waikato Night Glow event, and three girls were arrested for the assault and robbery of another girl on a city bridge.
"Parents and guardians have an obligation to the rest of the community to ensure they have control and can account for young people in their care while the rest of the community has a responsibility to report suspicious activity to police," Mr Lindsay said.
