Sydney teenager charged with armed robbery A TEENAGER who allegedly robbed two international students and another man in Sydney's east has been charged. The 18-year-old's alleged spree started in the early hours of Monday morning at university grounds in Kensington, police say. He pulled a knife on two students, 22 and 25, and demanded money. Both men gave him their wallets and he fled. He then threatened a 37-year-old man sitting in a parked car on the grounds. The man handed over his cash but then followed the alleged robber on foot and alerted police who were patrolling the area. The teenager tried to run but was caught and charged with two counts of robbery while armed with a dangerous weapon. Bail was refused and he's due before Central Local Court in late October.
