POLICE have arrested a 16-year-old girl who they believe played a role in two violent robberies over the weekend.
The Ipswich girl was allegedly part of a group of four people who confronted two teenage male victims at Tom Lenihan Park in Rosewood last Friday night.
The boys were verbally threatened and assaulted before handing over a mobile phone.
Police said the victims were then ordered to hand over their bicycles, but were able to ride away from their attackers.
In a separate incident at Dinmore train station on Saturday afternoon, an 18-year-old girl had to be hospitalised after being bashed and robbed.
Two men and two women allegedly confronted the girl at the station about 1pm, striking her in the face and body and stealing her money, mobile phone and watch.
Detectives from Ipswich's Child Protection Unit later charged the 16-year-old girl with two counts of robbery with violence in company, plus an additional count of going armed to cause fear, in relation to a separate incident in Dinmore at the weekend.
The girl will face the Children's Court on Monday.
