THIS 12-year-old was not afraid to cause a ruckus at a shopping mall or beat up an older boy.

When caught, the Secondary 1 (Normal Academic) student insisted that she was not involved and got her accomplices to lie.

For her incorrigible behaviour wily ways, she was rapped by Magistrate Wong Li Tein as dishonest and unremorseful, and sent to the Singapore Girls' Home for a month.

After which, she must stay at The Salvation Army's Gravehaven home for a year before serving the remaining six months of her probation at home. Her identity cannot be revealed as she is a juvenile.

In April, the girl joined her 14-year-old brother and other gang members to beat up a student who wanted to leave the gang.

After taking him to the 16th floor lift lobby of a block of flats, they told him that they would beat him for as long as their 17-year-old gang leader took to finish smoking her cigarette. When she lit up, they started punching and kicking the boy.

Three days later, the group attacked him again. Police were informed and the attackers were nabbed. In August, the Juvenile Court heard that the tween terror was close to her 14-year-old brother and had followed him into the gang.

Her brother, who tried to decieve the court with a letter from his teacher, stating that he was in class at the time of the offence, was placed on probation for 18 months.

Magistrate Wong said it would not be conducive to have both siblings on home probation at the same time. The girl was also ordered to attend a prison visit and perform 80 hours of community service when she turns 14.
