Police and judicial authorities in four countries have disclosed a series of grave incidents in recent days in which minors are alleged to be both perpetrators and victims, spanning a foiled school attack plot, multiple sexual assaults, and an abduction. The cases, reported from Canada, India, Russia, and Australia, involve suspects as young as 14 and victims as young as 5, according to official statements and court records.

In Canada, a 15-year-old boy in Bridgewater, Nova Scotia, now faces an additional charge of counselling another person to commit an indictable offence, on top of existing charges of uttering threats and conspiracy to commit murder. Police allege he and a 14-year-old boy in Manitoba planned simultaneous attacks on two schools—Park View Education Centre in Bridgewater and Rivers Collegiate in Rivers, Man.—after a tip from Interpol and the FBI in March. Investigators say they seized handwritten plans, imitation weapons, a crudely made imitation pipe bomb, and clothing bearing hate symbols. The Nova Scotia youth appeared in youth court on Thursday, and the matter was adjourned until July 14. The Manitoba teen, arrested separately, also faces conspiracy to commit murder and counselling the offence of murder, according to the Royal Canadian Mounted Police.

Separately, in Windsor, Ontario, a 15-year-old boy has been charged with two counts of sexual assault, one count of sexual interference, one count of forcible confinement, and three counts of assault after police say he gave alcohol to three girls aged 11, 13, and 16 at a residence and then sexually assaulted the 11-year-old and the heavily impaired 16-year-old. A 37-year-old woman was also arrested for obstructing police. In India, a 17-year-old girl was allegedly raped by three men near Porur, on the outskirts of Chennai, after being lured to a vacant plot of land, according to the All Women Police. One suspect has been arrested, and a hunt is underway for two others. The girl was taken to a private hospital by her parents after complaining of physical discomfort; doctors found evidence of penetrative sexual assault and alerted authorities.

Russian investigators in the republic of Dagestan have detained a man accused of violent sexual acts against his minor daughter, following a complaint by the child’s mother. The suspect, the girl’s father, had been granted custody by a court prior to the allegations. He has been remanded in custody while forensic examinations and witness interviews proceed. In Australia, a 15-year-old boy was arrested in Tarneit, west of Melbourne, after allegedly forcing a 17-year-old girl into a car as she arrived at Keysborough Secondary College in Springvale South on Friday morning. Police say the pair are known to each other; the girl was taken to hospital in a stable condition. No charges have yet been laid, and detectives continue to investigate.

All cases remain under active investigation, with some suspects yet to be apprehended and several court proceedings at preliminary stages. Authorities in each jurisdiction have declined to release identities of the accused minors, citing youth justice laws or privacy protections for victims.
